Abstract:
Embodiments of this disclosure provide a bias control apparatus and method of a modulator of an optical transmitter and an optical transmitter. By obtaining respective output power signals of a first Mach-Zehnder modulator and a second Mach-Zehnder modulator constituting the modulator of the optical transmitter, information on a phase bias may be extracted according to the two output power signals and an overall output power signal of the modulator of the optical transmitter, so as to control the phase bias by using the information, thereby efficiently improving a sensitivity of the control of the bias, and being applicable to various types of modulation formats.

Claim (Index 8):
The method according to  claim 7 , wherein the extracting information on the phase bias comprises:\n performing a first power adjustment on the first output power signal; performing a second power adjustment on the second output power signal; performing a first delay processing on the first output power signal after being performed the first power adjustment; performing a second delay processing on the second output power signal after being performed the second power adjustment; and to obtain the extracted information on the phase bias,\n subtracting the third output power signal by the first output power signal after being performed the first power adjustment, and \n subtracting the first delay processing and the second output power signal after being performed the second power adjustment and the second delay processing.
