Evaluation of All-Optical Demultiplexing in Millimeter-Wave Subcarrier-System for Wireless Communication
Paper i proceeding, 2006

In this paper, a scheme for multiplexing millimeter-wave carriers on a single optical carrier and using an all-optical millimeter-wave demultiplexer is presented. The optical demultiplexing of radio-over-fiber signals is based on dual sideband modulation with suppressed optical carrier combined with the filtering properties of dual over-written fiber Bragg gratings. The performance of the system is investigated using a single optical carrier and independent data modulated millimeterwave signals at 20 and 40 GHz. The signals are transmitted over optical fiber, demultiplexed and wirelessly distributed to a mobile unit. It is found that performance of the demultiplexing using fiber Bragg gratings gives less than -40 dB electrical power interchannel crosstalk and the spurious free dynamic range is measured to be 80 dB.Hz^(2/3). Furthermore, PSK, QAM and ASK PRBS modulated data up to 2.5 Gb/s are successfully transmitted through the wireless link.
