On-chip entangled photon source

摘要

Various technologies pertaining to an on-chip entangled photon source are described herein. A light source is used to pump two resonator cavities that are resonant at two different respective wavelengths and two different respective polarizations. The resonator cavities are coupled to a four-wave mixing cavity that receives the light at the two wavelengths and outputs polarization-entangled photons.

1. A photonic circuit comprising components implemented on a same substrate, the components comprising:
a first resonating cavity that receives light from an optical source and outputs light having a first wavelength; a second resonating cavity that receives the light from the optical source and outputs light having a second wavelength that is different from the first wavelength; and a four-wave mixing (FWM) cavity that receives the light having the first wavelength and the light having the second wavelength and outputs at least one pair of entangled photons.
