In general, SPAD is cooled down to the temperature around − 40 °C by 3-stage TEC for low dark noise operation. It increases the power consumption, footprint, and cost of single-photon detection module. By these reasons, room temperature operation of SPAD is one of key issues for current QKD system. It should be noted that a single-stage TEC ...
