摘要：
We proposed and experimentally demonstrated a novel method of optical mm-wave generation using only one Mach-Zehnder modulator and a direct-modulator, based on the method of optical carrier suppression. Using this proposed method, the 2.5 Gb/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 be more cost effective. (c) 2007 Wiley Periodicals, Inc.
