OPTICAL AMPLIFICATION CONTROLLER, METHOD FOR CONTROLLING SEMICONDUCTOR OPTICAL AMPLIFIER, AND OPTICAL TRANSMITTER

摘要

An optical amplification controller is constituted of a semiconductor optical amplifier, a temperature regulation unit for regulating the temperature of the semiconductor optical amplifier, and an optical gain control unit for regulating the temperature of the semiconductor optical amplifier by controlling the temperature regulation unit and varying the optical gain of the semiconductor optical amplifier. In this optical amplification controller, pattern effect can be suppressed even if the intensity of output light (intensity of amplification light) is increased.
