Optically injection-locked Fabry-Perot laser diodes based radio-over-fiber system for hybrid fiber-wireless access networks

Abstract

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.
