Abstract :
We have proposed and experimentally demonstrated a scheme of all-optical broadband subcarrier demodulation in the up-link of wavelength-division-multiplexing (WDM) millimeter-wave radio-over-fiber systems. In this scheme, the subcarriers of all the WDM channels can be demodulated by only one optical demodulation module, hence its cost can be reduced remarkably. Because of its all-optical implementation, it can offer more bandwidth. The radio-frequency power degradation introduced by the channel dispersion is also avoided in this scheme even when the conventional simple double-sideband modulation method is employed in the base stations.
