Abstract
An optical transmitter includes an optical modulator that is driven by a driving signal, an acquisition part, and a controller. The acquisition part obtains a relationship between a fluctuation of a parameter to adjust the driving signal and a fluctuation of a state of output light from the optical modulator due to the fluctuation of the parameter. The controller controls an amplitude of the driving signal on the basis of the obtained relationship.
Claims15
An optical transmitter comprising:
- an optical modulator that is driven by a driving signal;
- an acquisition part that obtains a relationship between a fluctuation of a parameter to adjust the driving signal and a fluctuation of a state of output light from the optical modulator due to the fluctuation of the parameter;
- and
- a controller that controls an amplitude of the driving signal on the basis of the obtained relationship.
A method for controlling an optical modulator that is driven by a driving signal, the method comprising:
- obtaining a relationship between a fluctuation of a parameter to adjust the driving signal and a fluctuation of a state of output light from the optical modulator due to the fluctuation of the parameter;
- and
- controlling an amplitude of the driving signal on the basis of the obtained relationship.
A controller that controls an optical modulator that is driven by a driving signal, the controller comprising:
- an acquisition part that obtains a relationship between a fluctuation of a parameter to adjust the driving signal and a fluctuation of a state of output light from the optical modulator due to the fluctuation of the parameter;
- and
- a controller that controls an amplitude of the driving signal on the basis of the obtained relationship.
