Abstract
An electro-absorption bias circuit may include a temperature sensor. The electro-absorption bias circuit may include a controller to provide a temperature-dependent control signal based on data received from the temperature sensor. The electro-absorption bias circuit may include a power supply to provide an output voltage based on the temperature-dependent control signal from the controller. The electro-absorption bias circuit may include an electro-absorption driving circuit to output a bias voltage applied to the output voltage provided by the power supply.
