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.
