Abstract:
A bias control apparatus and method of a modulator of an optical transmitter and an optical transmitter, in which by performing mutual interference on driving signals of two Mach-Zehnder modulators constituting the modulator of the optical transmitter, output optical fields of the two Mach-Zehnder modulators are correlated. Hence, an output power signal of the modulator of the optical transmitter contains information on phase bias. Thus, the phase bias may be controlled by using the output power signal, sensitivity of the bias control may be efficiently improved, and various types of modulation formats may be applied.

Claim (Index 8):
A bias control method of a modulator of an optical transmitter, the modulator of the optical transmitter comprising a first Mach-Zehnder modulator and a second Mach-Zehnder modulator, the method comprising:\n performing mutual interference on a first driving signal of the first Mach-Zehnder modulator and a second driving signal of the second Mach-Zehnder modulator, correlating output optical fields of the first Mach-Zehnder modulator and the second Mach-Zehnder modulator; and controlling a phase bias of the modulator of the optical transmitter according to an output power signal of the modulator of the optical transmitter.
