    摘要： In a method and apparatus for converting optical wavelength division multiplexed channels to wireless channels, the information carrying optical carriers are first de-multiplexed and each optical carrier is then extracted from the data using an optical channelizing technique. The optical frequency of each of the extracted optical carriers is then shifted by an amount equal to the desired wireless carrier frequencies in the broadband wireless channels. Optical heterodyning of the frequency-shifted extracted lightwave carriers with the original data-containing optical signals, which are mutually in phase coherence, in a photodetector results in a set of wireless carriers each modulated with the data carried by the corresponding optical channel.

    摘要： A method and apparatus for compensating for phase fluctuations incurred by an optical beam travelling through free space, especially a turbulent atmosphere. A transmitting station transmits a plurality of uniquely tagged optical beams through free space. The plurality of uniquely tagged optical beams are received at a receiving station, where a parameter of each uniquely tagged optical beam is quantified. Information associated with the quantified parameter for each uniquely tagged optical beam is then sent back to the transmitting station via a wireless feedback link. Using the information, the transmitting station adjusts at least one uniquely tagged optical beam to compensate for phase fluctuations.

    摘要： A system for wavefront aberration reduction of an incident optical beam. The system includes a spatial light modulator (SLM) for receiving the incident optical beam and forming an output optical beam. The output beam is aberration-reduced compared to the incident beam. An interferometer receives a portion of the output optical beam and generates an interference fringe pattern by introducing a phase shift to one part of the portion of the output optical beam, the interference fringe pattern being applied to the SLM. The interference fringe pattern is representative of the wavefront error of the incident optical beam and the interference fringe pattern activates the SLM such that the SLM performs wavefront error correction on the output optical beam.
