2.A. Propagation in a photonic crystal waveguide
In this section, we will use a standard tutorial example from RSoft??s FullWAVE tool to demonstrate how BandSOLVE
provides complementary information in designing photonic crystal devices. If you have access to a copy of FullWAVE,
you can perform both the simulations in FullWAVE and BandSOLVE, while reading. Even if you do not possess
FullWAVE, we provide sufficient screenshots in the following text to appreciate its results. Just ignore the instructions
relating to FullWAVE (which are prefixed with the notation FW,) and perform the BandSOLVE simulations.
2.A.1. Backing up the examples
BandSOLVE comes with a large set of example and tutorial files which we use extensively in this manual. Since it is
easy to accidentally overwrite these files in the course of experimenting with the tool, we recommend copying the entire
Examples directory in the RSoft install directory to another location, perhaps a subdirectory of your own home directory.
Then you can perform the exercises and tutorials on the copied set of examples and retrieve the original versions when
necessary. We suggest you do this now.
• Windows
Copy the directory c:\RSoft\Examples to a suitable location.
• Unix
Copy the directory /usr/local/rsoft/examples to a suitable subdirectory of your home directory.
