A millimeter-wave WDM-ROF system based on supercontinuum technique

In this paper, a new millimeter-wave (mm-wave) wavelength division multiplexing (WDM) system based on radio-over-fiber (ROF) technology is proposed. In this approach a multi-wavelength light source is obtained by supercontinuum (SC) technique, and mm-wave signals are obtained by using optical heterodyning method. We experimentally demonstrate the generation of optical carriers for 6-WDM channels, obtain 40 GHz mm-wave signals by employing optical heterodyne technique, and successfully achieve low error rate transmission of 2. 5 Gbit/s in WDM channels over a distance of 25 km in a G. 652 fiber. The experimental results verify that the proposed solution is feasible and cost effective.
