Abstract: The invention is a fiber-optic communication network, including a fiber-optic coupler having multiple fiber-optic ports and multiple optical transceivers which are individually connected to one of the fiber-optic pods. Each optical transceivers includes apparatus for transmitting to and receiving from the fiber-optic coupler, optical pulse signals in accordance with a predetermined code sequence of the transceiver, and optical amplifiers for amplifying the optical pulse signals. Each optical transceivers also includes apparatus for spectrally phase encoding/decoding, in accordance with the predetermined code sequence, optical pulse signals being transmitted to and received from its associated fiber-optic port, and apparatus for reconfiguring the code sequence in accordance with a user select signal. Each optical transceivers further includes detection apparatus for detecting a received optical pulse signal transmitted from another of the optical transceivers.

Abstract: An optically intraconnected computer and a reconfigurable holographic optical element employed therein. The basic computer comprises a memory for holding a sequence of instructions to be executed; logic for accessing the instructions in sequence; logic for determining for each the instruction the function to be performed and the effective address thereof; a plurality of individual elements on a common support substrate optimized to perform certain logical sequences employed in executing the instructions; and, element selection logic connected to the logic determining the function to be performed for each the instruction for determining the class of each function and for causing the instruction to be executed by those the elements which perform those associated the logical sequences affecting the instruction execution in an optimum manner. In the optically intraconnected version, the element selection logic is adapted for transmitting and switching signals to the elements optically.

Abstract: A random access memory addressing system utilizing optical links between memory and the read/write logic circuits comprises addressing circuits including a plurality of light signal sources, a plurality of optical gates including optical detectors associated with the memory cells, and a holographic optical element adapted to reflect and direct the light signals to the desired memory cell locations.

There are a plurality of storage cells for containing bits of binary information, the storage cells being disposed at the intersections of a plurality of row conductors and a plurality of column conductors. There is interfacing logic for receiving information from the computers directing access to ones of the storage cells. There are first light sources associated with the interfacing logic for transmitting a first light beam with the access information modulated thereon.

Abstract: An asynchronous, high-speed, fiber optic local area network originally developed for tactical environments with additional benefits for other environments such as spacecraft, and the like. The network supports ordinary data packet traffic simultaneously with synchronous T1 voice traffic over a common token ring channel; however, the techniques and apparatus of this invention can be applied to any deterministic class of packet data networks, including multitier backbones, that must transport stream data (e.g., video, SAR, sensors) as well as data. A voice interface module parses, buffers, and resynchronizes the voice data to the packet network employing elastic buffers on both the sending and receiving ends. Voice call setup and switching functions are performed external to the network with ordinary PABX equipment.
