Abstract
We discuss the highly-efficient on-chip transmission of quantum light from an integrated source. Under optical excitation, single photons emitted from a semiconductor quantum dot are injected into the propagating mode of a coupled photonic crystal waveguide. In such a system, slow-light effects induce Purcell enhancement of the coupled emitter increasing significantly the single-photon emission rates. Our system exhibits a single-photon emission rate into the propagating mode of 19 MHz with 23% efficiency. The high emission rates together with the coherence properties of the emitted single photons demonstrate the suitability of these systems for on-chip quantum information processing using quantum optical circuits.
