摘要：
A Light receiver generates a monitoring voltage according to an optical output of an LD element. The control circuit obtains a set value according to the ambient temperature around the LD element, and controls the optical output of the LD element on the basis of the comparing the result between the set value and the monitoring voltage. An adjustment section corrects the monitoring voltage on the basis of the set value and outputs the corrected monitoring voltage.
