S/N ratio of an upconversion detector dominated by upconverted spontaneous parametric down-conversion noise

In Mid-infrared Coherent Sources 2018 — 2018

We designed an upconversion detector (UCD) for 1575 nm operation. The signal-to-noise ratio of the UCD is investigated by considering the dependence of upconversion efficiency and upconverted spontaneous parametric down-conversion noise on pump power.
