The software application by Synopsys that includes the feature/module called RSOFT_MODEPROP is **OptoCompiler**.
**RSOFT_MODEPROP** (Mode Propagation) is a feature used in the context of optical design and simulation. It enables users to analyze and define the propagation of optical modes through various optical components. This can be particularly useful in designing waveguides, laser devices, and other photonic structures where understanding
