Theoretic and Experimental Study on mm-Wave Radio over Fiber System Based on OFM

摘要

This paper presents an overview on millimeter wave radio over fiber systems based on millimeter wave generation by optical frequency multiplication (OFM). The disadvantage of original OFM technique is checked and a novel bi-directional mm-RoF system based on new OFM technique using dual-drive MZM as high-order optical side-modes generator is proposed in principle and experimentally verified by a bi-directional mm-RoF system which not only produces 38 GHz information bearing signal in downstream, but also provides 40GHz local reference for down-conversion of upstream signal. Finally the advantage of OFM technique in reducing fading effect of fiber dispersion is theoretically proved.
