| Abstract: | Analysis indicates the importance of precise temperature control of single-photon detector used for quantum key distribution in infrared communication wavelengths. There exists an optimal operation temperature to satisfy the highest detection efficiency with the lowest dark counts and the dark counts are sensitive to the temperature. Precise temperature control based on ADN8831 is achieved for single-photon detector. The characteristics and applied circuit of the chip ADN8831 are presented in detail. The precision of the controlled temperature is 0.01℃. Photocurrent-Voltage and Dark-current-Voltage characteristics measured at different temperatures are presented. |
