Computes the band structures of photonic bandgap devices.
: Stores global variables to enable parametric design sweeps.
: Assigns the material profile (Step-Index, Graded-Index) and references the material from the database. 3. Parametric Design and the Symbol Table
Before running a long FDTD simulation, use the "View Index" feature to ensure your refractive index profile looks exactly as you intended. rsoft cad manual
RSoft accepts complex mathematical expressions within component fields.If you want a second waveguide to sit exactly 2 microns away from the first, set its X-position to w_core + 2.0 .When you update w_core , the entire geometry automatically updates without breaking the layout. 4. Advanced Geometry Techniques
Even with the manual in hand, photonic design has a steep learning curve. There are multiple avenues to accelerate your expertise.
: Act as a "master program" to launch and manage specialized modules such as BeamPROP, FullWAVE, and BandSOLVE. Computes the band structures of photonic bandgap devices
Launching RSoft CAD opens a highly specialized integrated development environment (IDE). Understanding its layout is critical for an efficient workflow.
The RSoft CAD manual covers a range of key features, including:
: Always toggle the 3D rendering window ( Ctrl+D ) to inspect your device. It reveals alignment gaps or dimension mismatches that are hard to spot in 2D. and click the endpoint.
Hardcoding dimensions directly into objects makes optimizations difficult. The resolves this by allowing you to define variables for variables like width, length, and radius. Implementing Variables Click the Symbol Table icon (fx) on the top toolbar. Add a new symbol (e.g., w_core = 0.5 ).

When simulations yield unexpected results, check for these common configuration issues: Probable Cause Corrective Action Grid size ( ) is too large or time step ( ) violates Courant stability.
