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： 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.

摘要： An optical computing system includes an input device, a converter and an optical computing device. The input device generates first light beams along selected ones of a first plurality of light transmitting paths. Each of the first light beams is representative of a digit of a number. The converter converts the first light beams into second light beams selected among a second plurality of light transmitting paths. Each of the second light beams is representative of the residue of the number modulo a given modulus among a plurality of mutually prime moduli. The converter generates, for each number, an ordered group of second light beams corresponding to an ordered group of residues modulo each of the mutually prime moduli. The optical computing device is coupled to receive the ordered group of second light beams from the converter for performing residue arithmetic operations.

摘要： An encryption and decryption system performs encryption and decryption using the residue number system. A binary input signal is converted into residue number system representation in a binary to residue converter. Pseudo random numbers, generated from pseudo random number generators, are then added to the converted input signal in modular, that is, residue number system, adders. The outputs of the modular adders are converted into binary or mixed radix digit representation and are then transmitted to the location of a decrypter. The transmitted binary or mixed radix digit signal is converted back into residue number system representation in another converter and is then decrypted by subtracting the pseudo random number sequence. This decrypted signal is then converted into binary representation. The binary representation of the decrypted signal resembles the input signal.

摘要： An information processor receives a residue number as an input and generates a mixed base number correspopnding to the residue number and a redundant residue digit corresponding to the residue number. The information processor includes a plurality of optical arithmetic and logic units (OALUs) arranged in channels and stages. Each digit of the residue number corresponds to a channel. Each channel produces a mixed base digit associated with the residue input number. The stages are serially arranged to successively generate mixed base digits corresponding to the residue number by performing modular multiplication and modular subtraction. Delay circuits are arranged parallel to the plurality of OALUs such that all of the mixed base digits are transmitted from the information processor at the same time. An additional channel of OALUs calculates the redundant residue digit based on the mixed base digits.

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 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.
