ABSTRACT:
According to an optical-receiving apparatus including an APD converting input light into an electric signal and a bias-voltage-control method used for the optical-receiving apparatus, a multiplication factor appropriate for the APD is predetermined and a multiplication factor used for the APD can be maintained at the level of the predetermined multiplication factor at all times according to a change in the ambient temperature of the APD so that the intensity of input light-transmitted to the APD can be monitored with accuracy. The optical-receiving apparatus further includes a bias circuit generating a bias voltage applied to the APD based on a control signal, a temperature-monitor circuit monitoring the ambient temperature, and an operating circuit that stores data on the predetermined multiplication factor and that controls the bias circuit so that the multiplication factor corresponding to the monitored temperature becomes the predetermined multiplication factor.
