چکیده انگلیسی
A full duplex radio over fiber system with frequency quadrupled millimeter-wave signal generation based on polarization multiplexing using a single-drive intensity modulator is proposed and experimentally demonstrated. At the central station, downstream signal modulated on the single-drive intensity modulator is polarization multiplexed with pure optical carrier by a polarization beam combiner (PBC) before transmitted over the single mode fiber to the base station. The single-drive intensity modulator is biased at the maximum transmission point to generate optical carrier and two second-order sidebands. At the base station, by simply adjusting the difference angle between the principle axis of polarizer and one principle axis of PBC to 135°, a frequency quadrupled millimeter-wave signal is generated. In addition, when the difference angle between the principle axis of polarizer and one principle axis of PBC is adjusted to 90°, the original pure optical carrier is recovered, which is wavelength reused to provide light source for the uplink to deliver upstream signal. A proof-of-concept experiment is performed. Pure optical carrier and 40â¯GHz millimeter-wave signal with 20â¯dB optical harmonic suppression ratio are obtained. The power penalties of the bidirectional links are less than 0.3â¯dB after transmitted over 10.5â¯km single mode fiber. The measured power fluctuation of the generated millimeter-wave signal is less than 1â¯dB in one hour, showing the proposed scheme is relatively stable for long-distance transmission system.
