Used for gratings, meta-surfaces, and photonic crystal structures to simulate an infinite array. 7. Troubleshooting Common RSoft CAD Layout Errors Symptom / Error Root Cause Corrective Action Discontinuous fields at waveguide junctions. Objects are not perfectly touching in space.
The entire RSoft layout is saved as an ASCII text file (usually with a .ind extension). Advanced users can bypass the GUI completely and write structural loops (e.g., defining photonic crystal hole arrays) using RSoft's native command syntax or command-line scripts. 5. Setting Up Simulation Monitors and Excitations
) and time-varying refractive index profiles controlled by external voltage variables. 3. Geometric Modeling and Component Construction rsoft cad manual
The manual dedicates an entire chapter to If your outputs vary wildly between runs, the manual advises:
Here are some tips and tricks for using the RSoft CAD manual: Objects are not perfectly touching in space
). Once your output power or effective index stops changing, your grid has converged, confirming your results are numerically stable. 6. Advanced Layout Strategies
Synopsys updates the with every major release. If you are using an older manual, you will miss critical new features. Advanced Automation: Scripting and MOST
Use built-in database models (like Lorentz-Drude) to simulate how materials behave across a spectrum of wavelengths.
PML (Perfectly Matched Layer) boundary conditions are too thin or too close to the structure.
: Define automated tracks along a waveguide to monitor power evolution along a curved route. 5. Advanced Automation: Scripting and MOST
