Tapered Waveguide
Application ID: 109451
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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
