摘　　要：A new radio-over-fiber system for use in hybrid fiber-wireless access networks is proposed and experimentally demonstrated,which is based on cascaded injection-locked Fabry-Perot laser diodes.It is verified that the proposed technique is able to achieve a good suppression ratio of an optical carrier suppressed(OCS) signal simultaneously through a programmable optical filter and by use of optical injection locking technique.A 60 GHz carrier with downlink baseband data has been generated and down converted to baseband signal in order to be characterized in our laboratory.A new radio-over-fiber system for use in hybrid fiber-wireless access networks is proposed and experimentally demonstrated, which is based on cascaded injection-locked Fabry-Perot laser diodes. It is verified that the proposed technique is able to achieve a good suppression ratio of an optical carrier suppressed （OCS） signal simultaneously through a programmable optical filter and by use of optical injection locking technique. A 60 GHz cartier with downlink baseband data has been generated and down converted to baseband signal in order to be characterized in our laboratory.
