摘要： An optical system includes an optical integrator, a readout mechanism, and an optical thresholder. The optical integrator is configured to perform temporal integration of an optical input signal having a first wavelength received at an input. The readout mechanism is coupled to the optical integrator and provides optical signals having a second wavelength to the optical integrator for measuring a state of the optical integrator. The optical thresholder is coupled to an output of the optical integrator and is configured to receive a signal representing a temporal integration of the optical input signal from the optical integrator and produce an optical signal identifying if an amplitude of the signal representing the temporal integration of the optical input signal is above or below a threshold value.

摘要： An optical signal amplitude discriminator incorporating the invention includes an optical loop having a nonlinear optical amplifier positioned a distance .DELTA.x from the loop's midpoint. The nonlinear optical amplifier is responsive to an applied optical saturating signal to exhibit an altered index of refraction which persists for a limited duration and induces a phase shift in an applied optical signal propagating therethrough. An input source applies both data and clock pulses to an unbalanced coupler, with the clock pulses having an input energy that is greater than the saturation level of the nonlinear optical amplifier and the data pulses manifesting an input energy that is less than the saturation level. The nonlinear optical amplifier amplifies and phase delays the first incident clock pulse. The counter-propagating clock pulse experiences a large phase shift and reaches the input coupler at a displaced time and results in a coupling of the clock pulse to the output terminal. Data pulses, exhibiting a lower energy, experience only a small relative phase shift and constructively interfere at the loop coupler.

摘要： A plurality of Acoustic Optic Modulators(AOM) are employed in the transmission subsystem of an optical data communication system for modulating different wavelengths of laser received from a grating with an electrical or radio frequency signal containing data or information to be transmitted. The modulated wavelengths of light associated with each AOM are recombined to form a shaped laser beam via a grating prior, and the shaped beams of laser light are multiplexed together for transmission over a fiber optic cable. A receiving station includes an optical decoding system for demultiplexing the shaped laser pulses, and for each shaped laser pulse detecting the individual modulated wavelengths of light comprising a desired spectrum, for extracting the data or desired information contained in each channel or wavelength of interest.

摘要： An optical demultiplexer includes an optical loop having first and second terminals and a mid point. A non-linear optical element is positioned in the loop at a distance .DELTA.x from the mid point. A first coupler is positioned in the loop and has a gating pulse applied which causes a change in the optical property of the non-linear optical element from a first state to a second state. A second coupler is optically coupled to the first and second terminals and has an input terminal for receiving a series of input optical pulses. The second coupler responds by inducing, for each input pulse, a pair of counter-propagating pulses in the optical loop. Control circuitry causes a gating pulse to be applied to the optical loop and to be timed to switch the non-linear optical element to from a first to a second state after one of the pair of counter-propagating pulses has passed through the non-linear optical element, but before the other counter-propagating pulse has reached the non-linear optical element. In this manner, one counterpropagating pulse is affected by the second state of the non-linear optical element and the other counterpropagating pulse is not, thereby enabling a differential signal to exit from the output of the second coupler to a detector.

摘要： A system and method for cancellation of RF interference in the optical domain. The system and method utilize two Mach-Zehnder electrooptic modulators biased for parallel counter-phase modulation. The method of signal subtraction is referred to as incoherent optical subtraction, since two independent laser sources serve as the optical carrier waves. The system has produced the broadband cancellation result while simultaneously recovering a 50 dBm signal which was initially “buried” under the broadband interference. The cancellation depths achieved by the system are due to the accurate channel tracking and precise time delays attainable with modern optical devices—unattainable with state-of-the-art electronic devices at the time of this writing.

摘要： An optical message distribution system is described which includes both a plurality of message sources and destinations. Each optical message includes a destination address portion and a data portion containing data signals. At a message source, an encoder generates, for each data signal of one kind, an optical pulse whose time position relative to a frame is indicative of a message destination address. An optical summer, common to all message sources combines the optical pulses onto an optical transmission medium and transmits them to an optical decoder associated with the each message destination. Each optical decoder determines if the time position of a received optical pulse relative to the frame is equal to a preset time delay, and if so, generates a data pulse of the one kind for the message destination.

摘要： An optical communication system is described wherein a message pathway is indicated by a destination address, manifested by an address time interval between a reference optical signal and an address optical signal. The optical communication system includes an optical switch for directing messages onto selected pathways. The switch includes a gate summer, and a reference circuit for applying a destination address portion of a message to the gate summer. A first delay circuit also applies the address portion of the message to the gating summer, while retarding it by a first address time interval. The gate summer sums the address portion from the reference circuit and the retarded address portion to produce a gating signal when the reference optical signal and address optical signal are time coincident. Switch means are further provided which are responsive to the gating signal to direct the message along a first selected pathway.
