摘要： Method of demultiplexing a composite signal light beam includes the steps of directing the composite signal light beam and a reference light beam at a photorefractive material, modulating the reference beam at a frequency about equal to the modulation frequency of a selected signal beam to be demultiplexed, and recovering the phase conjugate signal produced by interference of the reference beam with the composite signal light beam within the photorefractive material. The method also enables optical phase detection of the selected signal beam with respect to the reference beam.
