Institute for Microstructural Sciences - National Research Council of Canada, Ottawa, ON, Canada(Dated: September 26, 2011)We investigate single photon generation from individual self-assembled InGaAs quantum dotscoupled to the guided optical mode of a GaAs photonic crystal waveguide. By performing confocalmicroscopy measurements on single dots positioned within the waveguide, we locate their positionswith a precision better than 0:5 m. Time-resolved photoluminescence and photon autocorrelationmeasurements are used to prove the single photon character of the emission into the propagatingwaveguide mode. The results obtained demonstrate that such nanostructures can be used to realizean on-chip, highly directed single photon source with single mode spontaneous emision couplingeciencies in excess of ˘ 85 % and the potential to reach maximum emission rates >1 GHz.
