A frequency conversion system includes a bus waveguide, a first pump laser coupled to the bus waveguide and characterized by a first frequency, a second pump laser coupled to the bus waveguide and characterized by a second frequency, an input light combining device coupled to the bus waveguide and configured to combine light from the first pump laser and the second pump laser to produce a combined light, and a plurality of optical resonators coupled to the bus waveguide. Each optical resonator of the plurality of optical resonators has a respective resonance line width, wherein for each optical resonators of the plurality the respective resonance line width overlaps with a resonance line width of at least one adjacent optical resonator of the plurality of optical resonators, and wherein each optical resonator of the plurality is configured to generate output light at a converted frequency via frequency mixing.

Cascaded resonators photon pair source

A photon source includes a bus waveguide, a photon source pump laser coupled to the bus waveguide and a plurality of optical resonators coupled to the bus waveguide. Each optical resonator of the plurality of optical resonators has a respective resonance line width and a respective resonance frequency, wherein a bandwidth of the resonant center frequencies of the plurality of optical resonators is greater than a bandwidth of the photon source pump laser. The bus waveguide produces photons in response to receiving laser pulses from the pump laser.
