The software application by Synopsys that includes the RSOFT_DIFFRACTMOD feature/module is **RSoft Photonic Device Tools**.
**RSOFT_DIFFRACTMOD** is a module used for simulating and analyzing diffractive optical elements. It allows users to model the behavior of light as it interacts with complex optical structures, such as gratings, diffractive lenses, and other elements capable of manipulating light through diffraction. This functionality is
