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.

Single quantum emitter single photon source and producing a single photon stream

A photonic probe for atomic force microscopy includes: a cantilever including: a tip; a wing in mechanical communication with the tip; an extension interposed between the tip and the wing to synchronously communicate motion of the tip with the wing; an optical resonator disposed proximate to the cantilever and that: receives input light; and produces output light, such that: the cantilever is spaced by a gap distance from the optical resonator, wherein the gap distance varies as the cantilever moves relative to the optical resonator, and the output light differs from the input light in response to movement of the cantilever relative to the optical resonator; an optical waveguide in optical communication with the optical resonator and that: provides the input light to the optical resonator; and receives the output light from the optical resonator.
