Rsoft Cad Manual Jun 2026

Establishes the refractive index of the surrounding medium (e.g., air with , or a cladding material like Silicon Dioxide).

The manual clarifies the physics setup. It details how to define excitation sources (launch fields) and how to set boundary conditions (PML, Absorbing, Periodic) to ensure simulation results are accurate and free from artificial reflections.

PML (Perfectly Matched Layer) boundary conditions are too thin or too close to the structure.

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. Establishes the refractive index of the surrounding medium

The RSoft CAD interface replaces the need for decoupled design tools by embedding layout controls directly inside the master workspace.

): Sets the nominal operating wavelength, which scales grid sizes and material refractive indices.

One of the most referenced sections of the manual explains the Symbol Table . This feature allows users to parameterize their designs. Instead of hard-coding a waveguide width as "0.5 microns," the manual teaches users to define a variable (e.g., w ) and run parameter sweeps to see how width affects performance—a vital skill for optimization.

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.

Always run a series of short simulations while gradually reducing your grid size (
