ABSTRACT BODY:
Abstract We demonstrate heralded single photon generation in an
ultra-compact III-V semiconductor photonic crystal. Photons are
generated with a coincidence-to-accidental ratio over 60 and a g(2)(0)
of 0.06 representing the record fidelity to a single photon state for
a semiconductor waveguide device.
