Materials
Now, add materials for the cladding and the core of the waveguides. First, add the waveguide cladding material. By default, the first material will be assigned to all domains. In the second step, you will define the waveguide core material.
For this waveguide structure, GaAs is used as the cladding material and ion-implanted GaAs is used as the core material.
