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.
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 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 By mastering the RSoft CAD environment, designers can
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." This allows for easy parametric sweeps and optimization,
