Abstract:
There is provided an optical transmitter including a modulator, a signal generator configured to generate in-phase or anti-phase skew adjustment signals that are identical in amplitude and frequency as signals to be input into an I axis and a Q axis of the modulator, a skew adjuster configured to perform skew adjustment upon the skew adjustment signals, a light source configured to enter light into the modulator, a monitor configured to monitor light that has been modulated using the skew adjustment signals and output from the modulator, a power detector configured to detect power of monitor light, and a controller configured to determine a skew adjustment amount with which average power of the monitor light is at a maximum or minimum value as an optimum skew adjustment value while changing a skew adjustment amount of the skew adjuster.

Claim (Index 4):
The optical transmitter according to  claim 1 ,\n wherein the modulator includes an I-axis modulation unit, a Q-axis modulation unit, and a phase modulation unit, wherein a bias voltage of the phase modulation unit is set such that a phase difference between light passing through an I axis and light passing through a Q axis becomes a minimum in a state where an input signal is not modulated, wherein a bias voltage of the I-axis modulation unit and a bias voltage of the Q-axis modulation unit are set such that light passing through the I axis and light passing through the Q axis have same optical phase in a state where an input signal is not modulated, wherein the signal generator generates in-phase signals that are identical in amplitude and frequency as the skew adjustment signals, and wherein the controller determines a skew adjustment amount with which average power of the monitor light becomes a maximum as an optimum skew adjustment amount.
