| Abstract: | It is capable of detecting single photon on telecom wavelength windows around 1300 nm and 1550 nm to apply InGaAs/InP avalanche photodiodes to the Geiger mode.When avalanche photodiodes are operated in the gated mode to quench the avalanche,the single photon detector for 1550 nm is accomplished by using the magic-T junction to reduce the spike noise.When the operating temperature is 223 K,it is measured that the ratio of the dark count probability to the detection efficiency is 0.035. |
