摘要:
A light receiving device that receives a light signal includes: a plurality of avalanche photodiodes, in each of which receiving sensitivity is set in accordance with a bias signal that is provided; a plurality of level conversion units provided in association with the avalanche photodiodes, each of the level conversion units being configured to convert a level of a reference voltage for obtaining the bias signal so as to generate the bias signal and being configured to provide the bias signal to corresponding one of the avalanche photodiodes; and a control unit that generates a first control signal corresponding to a temperature of the light receiving device, and controls a level conversion amount of each of the level conversion units by using the first control signal.
