    摘要: A programmable optical arithmetic/logic device employs a first and second plurality of positionally encoded optical light paths. For arithmetic operations, these light paths represent residue numbers. The arithmetic/logic device includes first and second reordering units which are responsive to a third and fourth plurality of light sources serving to select one of a plurality of arithmetic or logic operations to be performed by the arithmetic/logic device. The arithmetic/logic device further employs an optical arithmetic/logic unit which is identically constructed for all of the selectable arithmetic/logic operations and which implements an optical table look-up function to obtain the desired output. Finally, the arithmetic/logic device used an output reordering device to reorder the output of the arithmetic/logic unit depending upon the originally selected arithmetic/logic operation. For arithmetic operations, the final output is provided as an output residue number representation.

    摘要: A fully optical A/D converter is disclosed in which the difference in light intensity from two outputs of a two-arm interferometer in each channel is detected. The difference in light intensity is varied in accordance with a phase shift in the light passing through one arm of the interferometer. The phase shift is accomplished by the use of a non-linear optical material, the optical properties of which are altered based on the characteristics of an input optical signal to be digitized. Thus, the difference in light intensity corresponds to the magnitude of the input optical signal.

    摘要: A technique for producing an integrated optics waveguide having a large index of refraction difference with respect to an otherwise similar waveguide that does not utilize the invention. A proton exchange region is formed in a lithium niobate substrate, and a titanium waveguide is formed in the substrate within the proton exchange region. The dimensions of the waveguide and proton exchange region are selected such that substantially all of the field of the lowest guided mode of the waveguide is contained within the proton exchange region. By utilizing such a waveguide as one arm of an interferometer formed in the substrate, a large optical path length difference between the interferometer arms may be created.

    摘要: A coherence multiplexed optical signal transmission system in which modulation is introduced into the system by modulating the optical carrier or source signal, rather than by modulating the optical path length of an interferometer arm. The system comprises a transmitter and receiver interconnected by an optical bus. The transmitter comprises a plurality of transmitter interferometers, each transmitter interferometer including a modulated optical source. The transmitter interferometers have optical path length differences that are greater than the coherence length of the associated source, and that differ from one another by an amount greater than the source coherence length. The receiver comprises a plurality of receiver interferometers having path length differences matching those of the transmitter interferometers. Multiplexing and demultiplexing means are provided for coupling optical radiation between the bus and the interferometers. A detection system is provided that includes an output terminal associated with each receiver interferometer. For each receiver interferometer, an output signal is produced at the associated output terminal when the optical radiation coupled into the receiver interferometer includes a component that has passed through a transmitter interferometer having an output path length difference equal to the optical path length difference of the receiver interferometer, to within the coherence length of the associated source.

    摘要: An apparatus and method for image analysis utilizing an optical-electronic hybrid device. A light source generates light through an alternating series of lenses and electronically addressable spatial light modulators to an optical correlation plane. A first modulator introduces an input image and a second modulator introduces a Fourier transformed reference image into the device. The device correlates the input image and the reference image in the optical correlation plane. The optical correlation plane feeds back information through a processor to the second modulator which varies a parameter of the reference image. The second modulator varies parameters to determine the greatest correlation between the input image and the reference image. The parameters at the point of greatest correlation are used together with the reference image to identify the input image.

    摘要: An optical computer arithmetic/logic unit using coherence multiplexing. A optical signal input into the device is distributed down two input channels. Each input channel contains different length optical fibers, or delay lines. To perform an operation, one delay line signal from each channel is selected. The two signals with their respective delays are multiplexed into output detectors which determine from optical interference the difference between the delay line lengths. The input from each channel coupled with the detected output can be set to perform residue arithmetic, or Boolean logic.
