Directional Coupler

Application ID: 14593


Two embedded optical waveguides in close proximity form a directional coupler. The cladding material is GaAs and the core material is ion-implanted GaAs. The waveguide is excited by the two first supermodes of the waveguide structure - the symmetric and antisymmetric modes. Two numeric ports are used on both the exciting boundary and the absorbing boundary, to define the two modes. A boundary mode analysis study sequence is set up, with four boundary mode analyses and a final frequency-domain study. The model demonstrates coupling from one of the waveguides to the other waveguide.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
