Waveguide structures can guide light waves; however, the number of propagating modes and their physical characteristics depend on the nature of light, structure, and material definition of the waveguide. The Advanced Mode Solver Module calculates the electromagnetic eigenmodes and propagation constants of optical waveguides using the Film Mode Matching (FMM) method and the Finite Differences (FD) method.
The Advanced Mode Solver Module helps users understand waveguide physics and optimize the response of their photonic components.
This module provides the first step on a fully integrated layout design flow.
