Abstract

We proposed high carrier suppression double sideband modulation using a Mach-Zehnder optical modulator with active trimming technique. The modulator has a pair of trimmers in the arms of the Mach-Zehnder structure. The trimmers can compensate amplitude imbalance in the Mach-Zehnder structure due to fabrication error, where the imbalance generates residual carrier in double sideband suppressed carrier (DSB-SC) modulation. We demonstrated high carrier suppression ration of SOdB in DSB-SC modulation at 10.5GHz, by using an integrated Mach Zehnder LiNbO3 modulator, where each arm has an intensity trimmer consisting of a sub Mach-Zehnder interferometer.
