The CAD defines the two crucial inputs for all simulation modules: material properties and device geometry. The is where you specify these properties. It includes a library of standard materials and allows you to define custom ones, either through analytical models (like Drude-Lorentzian-Debye fits) or by importing data from files in a specified format. This material data is then seamlessly passed to any simulation tool you choose to run.
The simplest method assigns a fixed real and imaginary number to a material. This works well for single-wavelength simulations where dispersion is negligible. The Material Editor
: Always toggle the 3D rendering window ( Ctrl+D ) to inspect your device. It reveals alignment gaps or dimension mismatches that are hard to spot in 2D. rsoft cad manual
Rather than hardcoding dimensions, the platform relies heavily on . If you change a single global symbol (e.g., Width_1 ), every dependent component scales automatically based on its programmed formula. The Multi-Pane View
The CAD is merely the interface; the real power lies in the solvers. The manual explains how to launch and interpret these, but understanding when to use each is crucial. The CAD defines the two crucial inputs for
The interface supports simultaneous multi-pane views, including X, Y, Z, and rotatable 3D perspectives Import/Export Capabilities: Users can import mask files in GDS-II, DXF, and CIF formats and export designs for mask fabrication. 2. Integrated Material Management
: The manual lists the command-line arguments for the CAD, allowing you to run heavy simulations on a server or cluster without opening the visual interface. This material data is then seamlessly passed to
This long article serves as a comprehensive guide to understanding and utilizing the RSoft CAD, breaking down its features, workflows, and the resources available—including the critical manuals—to help you excel in photonic design.
