Experimental realization of a low-noise heralded single photon source
arXiv:1007.2512 · doi:10.1364/OE.19.001484
Abstract
We present a heralded single-photon source with a much lower level of unwanted background photons in the output channel by using the herald photon to control a shutter in the heralded channel. The shutter is implemented using a simple field programable gate array controlled optical switch.
