A RoF system based on polarization multiplexing and carrier suppression to generate frequency eightfold millimeter-wave

Abstract In this paper, we propose and demonstrate a RoF system based on polarization multiplexing and carrier suppression to generate frequency eightfold millimeter-wave. The proposed scheme is based on one single drive Mach-Zehnder modulator and a polarization control system. By adjusting the modulation index, two-forth sidebands can be obtained. By controlling the polarization direction, our system can generate 80 GHz frequency eightfold millimeter-wave or recover optical carrier at the base station (BS). Finally, we verified the bit error rate (BER) of received optical power in the uplink and downlink. The received power penalty of uplink and downlink via 15 km single mode fiber (SMF) are 0.13 dBm and 0.34 dBm at the BER of 1 ×  10 - 9 respectively. This technology opens a new path for developments in microwave photonics.
