ABSTRACT:
An apparatus for, and a method for, achieving temperature compensation of an avalanche photodiode. The apparatus and method automatically detect the breakdown voltage of an avalanche photodiode immediately before the photodiode is operated and automatically applies the photodiode with a bias voltage always lower than the breakdown voltage of the photodiode, so that the multiplication factor of the photodiode is maintained constant.
