Abstract

We demonstrate an efficient and inherently ultra-low noise frequency conversion via a parametric sum frequency generation. Due to the wide separation between the input and pump frequencies and the low pump frequency relative to the input photons, the upconversion results in only approximate to 100 background photons per hour. To measure such a low rate, we introduced a dark count reduction algorithm for an optical transition edge sensor. (C) 2017 Optical Society of America
