Abstract

We describe a robust heralded single photon source based on parametric down conversion of CW 532-nm light in a periodically polled KTP waveguide. Low required pump power (sub-mW), reasonable operational temperature (43oC), high heralding efficiency (60%), and narrow spectral width of the heralded photons (sub-nm) make it an ideal light source for long-distance quantum communications.
