Abstract

Single-photons with high spectro-temporal purity are an essential resource for quantum photonic technologies. The highest reported purity up until now from a conventional silicon photonic device is 92% without any spectral filtering. We have experimentally generated and observed single-photons with 98.0 ± 0.3% spectro-tempral purity using a conventional micro racetrack resonator and an engineered dual pump pulse.
