Abstract

We demonstrate spontaneous parametric downconversion in straight GaAs and AlGaAs-on-insulator waveguides, which yield a maximum pair generation rate of 1.2 × 10 10 s −1 mW −1 , normalized to the pump power. The joint spectral intensity is directly measured via time-of-flight spectroscopy.
