Abstract
A thermally coupled imager includes a single photon detection pixel electrically isolated but in thermal communication with a thermal readout bus via a thermally conductive galvanic isolator, wherein the single photon detection pixel receives a single photon and produces thermal energy that is communicated to the thermal readout bus. A position and time of arrival of the single photon received by the single photon detection pixel is determined from voltage pulses produced by the thermal readout bus in response to receiving the thermal energy from the single photon detection pixel.
