Tessa quick reference guide Josselin Mouette École centrale de Lyon
josselin.mouette@ec-lyon.fr
 Tessa &version; version &version;, 07 July 2004 This guide describes how to get quickly started with Tessa and run your first FDTD simulations. It doesn't describe how Tessa works, neither is it a complete description of Tessa's features. Installing Tessa When Tessa is not available as a binary package for your system, installation is done through GNU autotools:
./configure make (as root) make install
You will need as prerequisites: The Hierarchical Data Format 5 library which is used to read and store all the data used by Tessa. Zlib, which is a prerequisite for HDF5 anyway. Necessary only if you use the provided module to generate the optical structures: Python, the scripting language used to generate the structures. NumPy, the Numeric Python extension. Numarray is not yet supported because it is too slow. PyTables, which brings in HDF5 support for Python. (optional) h5utils, a set of tools to manipulate HDF5 files, for e.g. cartography extraction. (optional) The Fastest Fourier Transform of the West library, version 3, which allows to output frequency spectrums. Creating your optical structure The first step before running the simulation is to "draw" the structure you want to simulate. You can generate it as you like, as long as it is in the HF5 format. If you already have tools that generate e.g. three-dimensional data files in text format, you can convert them to HDF5 using h5fromtxt from the h5utils package. If you start from scratch, you can use the python module provided with Tessa to generate a wide range of structures. First, create a file named e.g. tchat.py (the .py extension is for python scripts). This file should look like follows. First, import the Tessa module.
from tessa import *
Then, create an IndexFile instance, name it as you want.
asv=IndexFile(5,4,2.4,index=1.444)
The 3 first arguments are the size of the structure. It is generally convenient to express them in micrometers or meters, but it is not necessary. The optional index parameter is the default index in the structure. You can now fill your structure with geometric objects, e.g. cylinders.
asv.addobj(Cylinder(2.5,2,1,None,1,1.4,index=3.5)) asv.addobj(Cylinder(2.5,2,.7,None,1,1.4,index=1.444))
The two first required arguments for the Cylinder constructor tell the position of its center, the two following are the radii (the second radius being None, it is taken equal to the first), and the two final tell the vertical limitation for the cylinder. Order does matter: the second cylinder here will actually replace the first one where it is drawn. We obtain here a micro-ring.
asv.addobj(Block(1,1.3,-1,6,1,1.4,index=3.5)) asv.addobj(Block(3.7,4,-1,6,1,1.4,index=3.5))
These two blocks describe waveguides used to bring some optical signal to our micro-ring. The arguments are three couples of coordinates delimiting the block: x1, x2, y1, y2, z1, z2. Note that you can also use absorbing materials. Just add a absor = value parameter, with value being the absorption coefficient in m-1. Finally, we write the structure to HDF5 files.
asv.write("tchat1",delta_x=.05) asv.write("tchat2",delta_x=.1,oversampling=1)
Two files are written here: tchat1.h5 and tchat2.h5. You can write as many as you want, with a delta_x parameter defining the space step for the FDTD simulation. Be careful to use the same unit you used to define the size of the structure. Here, the second file is written using an oversampling of 1 instead of the default (which is 4). This is useful if you want to see the result immediately (the script will run 64 times faster), but the HDF5 file won't be accurate enough for launchinga simulation. Use it when designing the structures. You can draw several other types of geometric objects with this module. The complete documentation is accessible through python's internal help. Just run python in a shell, and, in the interpreter, type "import tessa; help(tessa)" (without the quotes). You can also easily make complex structures, such as photonic crystals, using loops just like in any other python script. If you don't know how to program in python, learn it. Even if you don't know how to program at all, achieving such things is easy. Once you have your script, process it:
python tchat.py
It can take several minutes, but you only have to run it once. This will generate the HDF5 file(s). You can control the result using h5ls, h5totxt and h5topng. Describing the simulation Once you have a HDF5 file containing the structure you want to simulate, you have to fill the simulation file. So, create e.g. tchat.fdtd. The .fdtd extension is purely for convenience, but it is generally a good idea. This file is a simple list of variable = value lines. Required parameters index_file = tchat.h5 Defines the HDF5 file containing the simulated structure. Incidentally defines the size of the simulation. delta_x = 0.1e-6 The spatial step of the simulation, in meters. Always use meters here, whatever unit you used when making the HDF5 file. it_max = 100000 The total number of iterations. One of the following: freq = 2e14 The frequency around which the simulation is achieved, in Hz. lambda = 1.5e-6 Ditto, but using the correspounding wavelength in meters. Optional parameters delta_t = 1.11e-16 The time step of an iteration. Defaults to a value slightly shorter than the maximum acceptable value for a stable simulation. block_size = 10 The size of the basic calculation block, in cells (that means, in units of delta_x. It affects performance when too small or too large. Defaults to 10. num_pml = 10 The size of the perfectly matched layers, in cells. Defaults to 10. Note that the PMLs are added outside the working space, so this parameter doesn't change the size of the actually computed structure. pml_refl = 1.e-3 The theoretical reflection of the perfectly matched layers under normal incidence. Defaults to 1.e-3, that is 0.1 %. One of the following: injection = sinus 10 Set the injection to a single frequency. The parameter gives the number of periods during which the signal takes place. injection = gauss 20 Set the injection to a gaussian spectrum around the base frequency. The parameter gives the relative frequency width in percent. injection_file = kikoo.dat Use the contents of a file as the amplitude of the injected signal. The file should be ASCII data, with one value per line, meaning one value per iteration. The default injection is a sinus with 10 periods of starting time. injection_pos = 10,50,25 The position of the injection, in cells. Defaults to the center of the simulation area. Currently, only dipole injection is supported. injection_dir = 0.707,-0.707,0 The direction and maximal amplitude of the injection, in C.m. The computed injection is multiplied by each of these factors for the directions x, y and z respectively. Defaults to 0,0,1. As a consequence, by default, the computed numerical values are normalized for a dipole moment equal to 1 C.m. Defining the output Each of these parameters can be used as many times as you want, to have multiple outputs. output_cartoE = 0-2000/100 Output cartographies for the electric field (all three components), in the HDF5 format. The parameter explains at which iterations the output should be made. The above example makes this output every 100 iterations during the first 2000 iterations. Any of these parameters can be omitted, defaulting respectively to zero, the last iteration and 100. output_cartoH = /1000 Same as above, but for the magnetic field. output_ponctE = 60,70,25 Output the three components of the electric field at each iteration, at the point defined by the three coordinates, in unit cells. The output file has 4 columns: the time in seconds, and the field in the 3 directions. If Tessa was built with support for discrete Fourier transforms, a file containing the Fourier transform is output as well, the first column containing the frequency in hertz. output_ponctH = 60,70,25 Same as above, but for the magnetic field. output_poynting = 45-55,70,45-55 Output the flow of the Poynting vector through a rectangular surface. The size of the surface is defined by two couples of coordinates and its position is defined by one single coordinate, in unit cells. The coordinates are always in the x, y, z order; the one being alone defines the direction of the plane. total_loss = 1 Output the flow of the Poynting vector through all external surfaces. This is the total power lost by the system. Defaults to 0 (disabled). Invoking Tessa Run the simulation you defined above by typing tessa tchat.fdtd and wait. Tessa is believed to run faster than commercial implementation of the FDTD algorithm, but this algorithm is nevertheless slow. Extracting the results Viewing cartographies The HDF5 format used for the output contains three-dimensional data. It is possible to directly view this data using tools like Vis5d+ or MayaVi, but it is generally more convenient to extract it as two-dimensional pictures. You can do it very easily using h5topng from the h5utils package. For example, to extract the data for the y component of the electric field at z = 25 (in unit cells), just run:
h5topng -Z -c bluered -S 3 -C tchat1.h5 -d y_comp -z 25 E*.h5
You can refer to the h5topng manual for more information. Viewing spectra The .dat files where spectra are written can be directly used for visualization. Just import them in a spreadsheet, or use xmgrace.

That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. tessa-0.3.1/py-compile0000755000175000017500000000474510041367741011574 00000000000000#!/bin/sh # py-compile - Compile a Python program # Copyright 2000, 2001 Free Software Foundation, Inc. # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
