"Plug and Play" single photons at 1.3 mu m approaching gigahertz operation

We report a "plug and play" single photon source, fully integrated with an optical fiber, emitting at 1.3 mu m. Micropillars were patterned on a single layer InAs quantum dot wafer to guarantee a single pillar per fiber core. The single exciton peak filtered with a tunable optical filter was fed to a Hanbury Brown and Twiss interferometer, and the second order correlation function at zero delay was less than 0.5, indicating single photon emission. The measured decay dynamics under double-pulse excitation show that the single photon device can be operated at speeds greater than 0.5 GHz. (C) 2008 American Institute of Physics.
