Abstract

Soliton switching based on spatial solution emission requires the cladding material has high enough nonlinear change of the index. We describe the design of a waveguide that has nonlinearity enhancement at the boundary due to deep level states excitation. The example material is the Al_xGa_1-xAs. This material has El₂ related deep level states which become deeper as the AlAs mole fraction increases so that we can suitably choose the bandgap, and therefore the deep levels to match the working wavelength. The distribution of the guided mode field is also modified by the design of the waveguide geometry to facilitate an inner built electric field which is responsible for the nonlinearity enhancement.
