摘要： An optical communication module includes a laser that emits laser light, and an electro-absorber that absorbs the laser light, which is emitted from the laser, according to a voltage modulated based on a modulating signal and a bias voltage. The optical communication module detects data that varies correlatively with the temperature of the electro-absorber, and sets the bias voltage, which is associated with the detected data, on the basis of relational data specifying at least the relationship between the bias voltage and the data.
