| Abstract: | The selected APDs which have higher punch through voltage are used to prove single photon detection at 1550 nm communication wavelengths at temperature of above 253 K. In the experiment,a controllable nonlinear current limiting circuit is used to protect the APD operated in Geiger mode at high temperature. Single photon detection at 1550 nm communication wavelengths,cooled by a thermo-electrical cooler,were experimentally demonstrated at temperature of 257.8 K. Its dark count is 3.13×10－5 ns and single photon detection efficiency is 2.08%. The experimental data indicate that it is possible to realize single photon detection at higher temperature. The APDs operated at the temperature of above 253 K can simplify the cooling device greatly. |
