Abstract
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.
Claims19
A method comprising:
- coupling a pump laser to a bus waveguide;
- coupling a plurality of optical resonators to the bus waveguide, wherein each optical resonator of the plurality of optical resonators has a respective resonance line width and a respective resonance center frequency, wherein the frequency span of the resonant center frequencies of the plurality of optical resonators is greater than a bandwidth of the pump laser;
