Abstract
A photon detection device and method of fabricating a photon detection device are provided. The photon detection device comprises a first input terminal for receiving a DC input voltage, a second input terminal for receiving an AC input voltage and a bias tee connected to the first and second input terminals and configured to combine the AC and DC input voltages to form a combined voltage on an output of the bias tee. A first single photon detector is connected to the output of the bias tee and configured to receive the combined voltage from the bias tee, register a detection signal based on only a single photon being incident on the first single photon detector and output the detection signal indicative of the detected photon. A first output terminal is connected to an output of the first single photon detector for outputting the detection signal. The photon detection device is formed in a single integrated circuit.
