Nonlinear interaction in nanowaveguides

Integrated silicon nitride electro-optic modulators with atomic layer deposited overlays

We present an integrated electro-optics modulator. Existing SiN waveguides have been enriched by a cladding of ZnO presenting a second order nonlinearity. We report phase modulation using this hybrid SiN waveguide.
