Abstract

The transfer printing of aluminium gallium arsenide (AlGaAs) micro-disk resonators onto a silicon-on-insulator (SOI) waveguide platform is demonstrated. The integrated resonators exhibit loaded Q-factors reaching 4×104, and the vertical assembly approach al-lows selective coupling to different spatial mode families. The hybrid platform’s non-linearity is characterized by four-wave mixing (FWM) with a measured non-linear coefficient of γ=325 (Wm)−1, with the devices demonstrating minimal two-photon absorption (TPA)and free-carrier absorption (FCA) losses that are inherent to SOI at telecommunications wavelengths.
