Paper Abstract

We experimentally demonstrate a demultiplexing scheme for the frequency-interleaved dense wavelength division multiplexing (DWDM) radio-on-fiber system using an arrayed-waveguide grating (AWG). We first show the principle of the frequency-interleaved DWDM radio-on-fiber and possible configurations of multiplexing and demultiplexing (DEMUX) schemes using an AWG. In the experiment, 25-GHz separated 2-channel optical double sideband signals modulated by a 60-GHz millimeter-wave carrying a 156 Mbps data are optically multiplexed by frequency interleaving. The power penalty after DEMUX, which was due to interchannel interference, was less than 0.5 dB. We also made a transmission experiment in 25-km standard single mode fiber (SMF). No noticeable power penalty in the received data due to transmission was observed. This is because carrier and only one of the sidebands are detected in the proposed DEMUX scheme.
