Abstract
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.
Claims8
An optical communication module comprising:
- a laser light emitting device that emits laser light;
- an electro-absorption optical modulation device that absorbs the laser light, which is emitted from the laser light emitting device, according to a voltage modulated based on a modulating signal and a bias voltage;
- a detection unit that detects data which varies correlatively with the temperature of the electro-absorption optical modulation device;
- and
- a setting unit that sets a bias voltage, which is associated with the data detected by the detection unit, on the basis of relational data specifying at least the relationship between the bias voltage and the data.
A control method for an optical communication module including a laser light emitting device that emits laser light, and an electro-absorption optical modulation device that absorbs the laser light, which is emitted from the laser light emitting device, according to a voltage modulated based on a modulating signal and a bias voltage, comprising the steps of:
- detecting data that varies correlatively with the temperature of the electro-absorption optical modulation device, and
- setting the bias voltage, which is associated with the data detected at the detecting step, on the basis of relational data specifying at least the relationship between the bias voltage and the data.
