摘要： An electro-optical device includes a vertical cavity surface emitting laser, a heterojunction light emitting device and heterojunction phototransistor on a semiconductor substrate. Layers of the heterojuncticn phototransistor and the heterojunction light-emitting device are electrically and optically coupled so there is regenerative optical and electrical feedback between them. Layers of the heterojunction light-emitting devices are proton implanted to control the feedback. Plural such devices are electrically and optically coupled together to perform logic functions, such as EXCLUSIVE OR, in response to optical signals.

摘要： Operation results for all combinations of input optical signal values to be operated are previously determined and substantially parallel light beams reflecting the operation results for all combinations are generated. Selectors for selecting transmission area of the input light beams in accordance with digital information born by optical signals are arranged for the respective optical signals along the direction of propagation of the light beams. Through the logically cascade-connected selectors, an optical signal corresponding to a combination of current input optical signals is selected from the operation results for all combinations.

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 common substrate supports a plurality of waveguides numbering one more n the number of bits in the binary addends to be summed. Linearly polarized light is transmitted along each of the waveguides and a plurality of electrodes connectable to an electrical potential representative of a binary bit. The electrodes have discrete lengths contiguous to the waveguides for causing .pi.-radian phase retardation of light propagation upon application of the electrical potential. A polarization separator receives the output of each waveguide and produces signals commensurate with orthogonally polarized components. Photo detectors responsive to the signals representing each of the components produce commensurate electrical output signals which are, in turn, amplified and compared in an analog comparator for producing a binary output signal representative of the relative amplitudes of each pair of signals representing the orthogonally polarized components in each of the waveguides.
