    Abstract: The present invention discloses an apparatus and a method for controlling a driving amplitude of a DQPSK transmitter. The method includes: a DQPSK modulator modulating an optical signal emitted from a CW and without adding with modulated signal; a modulator feedback control unit is connected with a first bias point, a second bias point and a third bias point and controls the first bias point, the second bias point and the third bias point according to a part of the optical signal modulated by the DQPSK modulator; controlling the driving amplitude of a driver I according to temperature change of the driver I; controlling the driving amplitude of a driver Q according to temperature change of the driver Q. The present invention can be used to simplify complexity of the control circuit of the DQPSK transmitter, and therefore no extra optical signal-to-noise ratio cost would be created.
