Components: These include basic shapes like blocks, cylinders, and polygons.Segments: Specifically designed for waveguide-based structures, segments can be straight, tapered, or curved (S-bends and arcs).Profiles: Every object is assigned a "profile" which dictates its refractive index or optical properties. Profiles can be simple dielectric constants, complex dispersive materials from a library, or user-defined anisotropic tensors.
A key feature of the RSoft CAD is its use of symbolic variables. Rather than entering static numerical values for lengths or widths, users can define variables (e.g., "width = 0.5"). This allows for easy parametric sweeps and optimization, as changing a single variable updates all dependent objects in the design. Object Construction and Properties rsoft cad manual
The CAD tool also supports a "Layer" system. This is particularly useful for integrated photonics (PIC) design, allowing users to group objects into specific fabrication levels, such as the silicon core layer, cladding layer, or metal contact layer. Material and Index Modeling Rather than entering static numerical values for lengths
The RSoft CAD Environment serves as the foundational design interface for the Synopsys RSoft Photonic Device Tools. It acts as the control center where users define the structural geometry, material properties, and simulation parameters for photonic components before passing them to specific solvers like BeamPROP, FullWAVE, or DiffractMOD. Design Hierarchy and Interface This is particularly useful for integrated photonics (PIC)
By mastering the RSoft CAD environment, designers can efficiently prototype complex optical structures, ranging from simple waveguides and gratings to advanced photonic crystals and metasurfaces.
Users build structures using built-in primitives. Each object is defined by its start and end coordinates, which can be specified in either absolute terms or relative to other objects.
The CAD interface uses a hierarchical approach to design. At the top level is the Global Settings dialog, where fundamental simulation parameters—such as the free-space wavelength, background refractive index, and dimension scales—are established. The workspace itself is a 3D coordinate system (X, Y, Z) where users place various geometric "objects."
