Self-homodyne systems with polarization multiplexed carrier offer an LO-less\ncoherent receiver with simplified signal processing requirement that can be a\ngood candidate for high-speed short-reach data center interconnects. The\npractical implementation of these systems is limited by the requirement of\npolarization control at the receiver end for separating the carrier and the\nmodulated signal. In this paper, effect of polarization impairments in\npolarization diversity based systems is studied and modeled. A novel and\npractical adaptive polarization control technique based on optical power\nfeedback from one polarization is proposed for polarization multiplexed carrier\nbased systems and verified through simulation results. The application of the\nproposed concept is experimentally demonstrated also for a QPSK system with\npolarization multiplexed carrier.\n
