Abstract

The AlGaAsOI material platform offers great promise as a source of quantum states of light that can be utilized for enhanced sensing and metrology beyond the standard quantum limit. Here we focus on preliminary results from AlGaAsOI microring resonator sources that demonstrate a 1000-fold improvement in the brightness of entangled photon pairs compared to state-of-the-art chip-scale sources. The source maintains high single photon purity < 99% and time-energy entanglement visibility < 95%.
