Dispersion-engineered AlGaAsOI waveguides for on-chip SPDC — •Marlon Placke and Sven Ramelow — Humboldt-Universität zu Berlin, Germany

We present AlGaAs-on-insulator as a promising nonlinear optics platform with C-band compatibility. Combination of the semiconductor’s ultra-high material nonlinearity with submicron waveguiding renders possible an efficient interface with great potential for full on-chip integration - provided phasematching can be achieved. Our simulations elucidate the capabilities of dispersion engineering on this platform and predict that modal phasematching is feasible for SHG and SPDC at telecom wavelengths.
