A tapered optical waveguide structure is used for matching two waveguides having different geometric cross sections and/or different material parameters. The tapered waveguide has one geometric cross section at the input plane and another cross section at the output plane. In between these planes, the core width changes linearly with the propagation distance.

This model demonstrates how to define a user-defined phase and wave vector for the Electromagnetic Waves, Beam Envelopes interface, when used with Perfectly Matched Layers (PMLs). The PMLs are used for absorbing the radiation that is not matching the port mode fields.
