Uses Finite-Difference Time-Domain (FDTD) for grid-based EM wave propagation.

Structures with high refractive index contrasts, sharp bends, gratings, photonic crystals, and resonant cavities. CAD Checklist: Ensure your grid sizes are small enough (

You can create complex structures using basic building blocks like segments, circles, and polygons. The Array Layout Utility

RSoft CAD (often invoked as xbcad or RSoft CAD Layout) is the graphical layout and pre/post-processing environment for the RSoft photonics toolset (BeamPROP, FullWAVE, DiffractMOD, GratingMOD, FemSIM, BandSOLVE, etc.). It provides a visual editor to build planar and 3D device geometries, assign materials and boundary conditions, create mesh and simulation regions, launch solvers, and view results.

This chapter is essential for creating physically accurate simulations. It details how to:

Define the target measurement (e.g., maximize transmission in Monitor 1). This chapter is essential for creating physically accurate

Refractive index contrast is inverted or profile parameters are wrong.

RSoft CAD is a layout and design tool within the Synopsys RSoft Photonic Component Design Suite used to create, edit, and export 2D photonic device geometries and mask layouts for simulation and fabrication. It supports drawing primitives, boolean operations, layer management, grid/snapping, text/annotations, and exports common file formats for downstream simulators (e.g., BPM, FDTD) and mask generation.
