Furthermore, the manual is updated with each RSoft release. As of 2024-2025 releases, new features like and Python-based automation hooks are only documented in the official manual.
: Use the Arc or S-Bend tool for low-loss routing. Object Property Dialog Box
: Calculates the fundamental or higher-order guided mode of your input waveguide and launches it cleanly.
Before drawing, set the background material (usually air or a cladding material) and the grid size. The grid size is critical; it must be small enough to resolve the optical field but large enough to keep simulation times reasonable.
The CAD's material model is extensible, allowing for the simulation of cutting-edge materials like graphene. The software includes built-in material functions, such as graphene_real() and graphene_imag() , which calculate the complex refractive index of graphene as a function of wavelength, chemical potential, temperature, and other parameters. Pre-defined isotropic and anisotropic graphene models are available in the material library, enabling users to accurately simulate the unique optical properties of this 2D material within their photonic designs. rsoft cad manual
Double-clicking any object opens its properties window. Every component relies on these key parameters:
Define the unit cell properly in the CAD and apply the correct periodic boundary conditions. 6. Advanced CAD Features and Best Practices Using MOST for Parameter Sweeps

The CAD manual acts as the "anchor" for several specialized simulation engines: Furthermore, the manual is updated with each RSoft release
: Every parameter (width, position, refractive index) can be defined using arithmetic expressions and variables. This allows you to update an entire design by changing a single variable value. Property Access
The RSoft CAD is designed to work seamlessly across multiple simulation engines without needing to re-import designs. Beamprop Rsoft Training Material | PDF - Scribd
The RSoft CAD (Computer-Aided Design) environment is the foundational user interface for Synopsys’ RSoft Photonic Device Tools. It serves as the central hub for designing, simulating, and analyzing photonic devices, ranging from simple waveguides to complex photonic integrated circuits (PICs). The RSoft CAD Manual is the primary reference document for unlocking the full potential of this simulation suite.
Once you are comfortable with the basics, the CAD environment supports highly advanced design flows. Object Property Dialog Box : Calculates the fundamental
The RSoft CAD manual typically covers how to interface with these key simulation tools: : For waveguide and fiber applications.
While the CAD can handle complex photonic integrated circuits (PICs), its core workflow is best illustrated with a simple example. The following steps are based on standard simulation guidebooks and demonstrate the process for a straight channel waveguide.
: Enable grid snapping for manual drawing to prevent sub-nanometer alignment offsets. Offsets can cause artificial scattering in simulations.
