  • Single quantum emitter single photon source and producing a single photon stream
    Patent number: 11451306
    Abstract: A single quantum emitter single photon source produces a single photon stream and includes: a single-mode excitation waveguide that receives a pump light, propagates pump light as resonant excitation light, and produces evanescent excitation light; a separation gap between single-mode excitation waveguide and a multi-mode intermediate waveguide; a multi-mode intermediate waveguide that: includes a single quantum emitter, evanescently receives the evanescent excitation light from the single-mode excitation waveguide, propagates the evanescent excitation light as resonant excitation light, and subjects the single quantum emitter to the resonant excitation light such that the single quantum emitter produces emitted single photons; and a single-mode output waveguide that receives the emitted single photons from the multi-mode intermediate waveguide and propagates the emitted single photons as an emitted single photon stream.
