COHERENT PHASE AND FREQUENCY DETECTION USING SUM-FREQUENCY MIXING IN NON-LINEAR WAVEGUIDES
摘要
A plurality of signals are mixed in a non-linear waveguide for generating a near field sum frequency output pattern. The near field output pattern is monitor ed for changes which correspond to changes in the phase relationship between the plurality of signals. A grating provides a mask through which the near field pattern may propagate. Detectors positioned above the grating at predetermined locations measure the intensity of the near field pattern and a change in the phase relationsh ip between the input signals is determined from a change in the intensity of the near field output pattern.
