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 1):
A bias control apparatus to couple to a modulator of an optical transmitter, the modulator of the optical transmitter including a first Mach-Zehnder modulator and a second Mach-Zehnder modulator, the apparatus comprising:\n at least one memory to store instructions and information; and at least one hardware processor to perform, the at least one hardware processor coupled to the at least one memory to execute the instructions to perform, and/or the at least one hardware processor is to perform,\n obtain a first output power signal of the first Mach-Zehnder modulator, a second output power signal of the second Mach-Zehnder modulator and a third output power signal of the modulator of the optical transmitter; \n extract information on a phase bias of the modulator of the optical transmitter, according to the first output power signal, the second output power signal and the third output power signal; and \n control the phase bias of the modulator of the optical transmitter, according to the extracted information on the phase bias of the modulator of the optical transmitter.
