Why Use RSoft GratingMOD CMT

Simulate fiber gratings, waveguide gratings, Bragg gratings, and wavelength-selective photonic devices using efficient coupled mode theory (CMT) analysis.

RSoft GratingMOD uses coupled mode theory (CMT) to analyze and synthesize optical gratings in fiber and integrated photonic devices. Engineers can model grating-assisted couplers, fiber Bragg gratings, long-period gratings, waveguide gratings, and other wavelength-selective structures to evaluate spectral performance, coupling behavior, and filtering characteristics before fabrication. This approach provides efficient simulation of grating-based photonic devices without requiring more computationally intensive electromagnetic methods. Based on the RSoft portfolio description, GratingMOD is specifically positioned for analyzing and synthesizing complex grating profiles in optical fibers and integrated waveguide circuits.
