3.B. Design Procedure
The following outlines the design and simulation procedure:
1. Generate CAD files for the input and output star couplers as well as the full layout via Utility/WDM-Router-Layout. The utility STARGEN is provided for this purpose. Modify CAD files as appropriate to set waveguide and simulation parameters.
2. Generate script files for the simulation via Utility/WDM-Router-Simulation. The corresponding utility is SCRIPGEN.
3. Execute the scan#.scr script file for each distinct input port # to perform a wavelength scan (via Run/Run-Script).
4. At each wavelength, simulate the input star coupler first, which will generate a "mode list" at the output.
5. Run starout.scr which will process the mode list based on the waveguide grating, generate an input to starout.ind, and run starout.ind to determine the output at a specified wavelength.
6. Transmissions at each output port are collected in the scan#.dat file and at the end of scan, a WinPLOT file is generated to show the wavelength spectrum of the AWG router. Each step is described in detail in subsequent sections.
3.C. Using the WDM Router Layout Utility
This section outlines the usage of the WDM Router Layout Utility.
