Instead of entering 3.2 for a waveguide width, define a variable named w_core in the Symbol Table. If you change w_core later, every geometric object referencing that symbol updates automatically. Mathematical Expressions
: Linear or parabolic transitions can be applied to smoothly match a narrow single-mode waveguide to a wider multimode interference (MMI) section. 4. Setting Up Simulation Parameters
Upon launching, you will click the "New Circuit" button (often represented as a blank paper icon). This brings up the "Startup Window," sometimes referred to as "Global Settings". Here, you will define the fundamental simulation dimensions, set the background material (e.g., SiO₂ with a refractive index of 1.45), and define the free space wavelength (typically 1.55 µm for telecom applications). rsoft cad manual
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.
Ensure connected segments share exact coordinate nodes. Zoom in closely or use grid-snapping options to prevent accidental gaps that cause artificial optical scattering. Instead of entering 3
Optimized transition paths for shifting a waveguide laterally over a short propagation distance. 4. Parametric Design and Scripting
A key advantage is that designs created in the CAD Environment do not need to be re-imported or converted when switching between different simulation modules. The CAD tools are included with every RSoft passive component simulation tool, making them an integral part of the workflow for designing waveguide devices, optical circuits, and other photonic structures. Here, you will define the fundamental simulation dimensions,
