Optical mm-wave generation by using direct-modulation DFB laser and OCS modulation scheme

We proposed and experimentally demonstrated a novel method of optical mm-wave generation using only one Mach- Zehnder modulator (MZM) and a direct-modulator based on the method of optical carrier suppression. Using this proposed method, the 2.5Gb/s data channel was successfully transmitted over 20 km for downstream with less than 1-dB power penalty. Therefore the system configure of mm-wave generation can be further simplified and more cost effective. The transmission performance of system was analyzed theoretically and numerically. According to our research, the mm-wave generated by this scheme can be immune fiber dispersion, and the configuration of the base station can be simplified and the cost is thus reduced.
