Abstract: An optical time integrating correlator is fabricated in integrated optical form. This integrated optical implementation comprises a number of integrated components including an optical waveguide on a substrate, a diode laser, a guided wave lens, an electro-optic beamsplitter, a pair of surface acoustic wave transducer for generating first and second counterpropagating surface acoustic waves, a spatial filter and a detector array.

Abstract: A tunable organic dye laser having an acoustic-optic beam deflector, a fod Lyot filter and a diffraction grating which produces a periodic, discrete (or digital) output. The period between discrete wavelengths in the output of the laser are easily varied electronically.

Abstract: A data bus coupler having a fiber optic bundle input, a separate optical ulator or detector (described in a concurrent disclosure by the same inventors) attached to each fiber of the bundle for adding information to, extracting information from, or detecting the information conducted by the fiber, and an output wherein the fibers are rejoined into a fiber optic bundle. The optical modulator/detectors are double heterojunction semiconductors that are switched "on" by reverse biasing and with large voltages they may act as photoavalanche diodes when detecting incident radiation.

Abstract: An electro-optically tuned organic dye laser having an electro-optic cell d a diffraction grating. A varying electrical field is supplied to the cell to cause the laser beam to be swept across the stationary diffraction grating which reflects a specific wavelength for each angle of incidence.
