All-optical mm-wave generation by using direct-modulation DFB laser and external modulator

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...

Description
Summary: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. © 2007 Wiley Periodicals, Inc.
