摘要： A Terahertz Optical Asymmetric Demultiplexer (TOAD) having preferably two non-linear elements (NLES) in which the extinction ratio is enhanced by saturating both NLEs when closing a switching window. A data signal input on one port of the TOAD is split onto two optical paths, each including one NLE. The optical paths converge at an output port. To start a switching window, a first control signal is input on an optical path that includes only one of the two NLEs. To close a switching window, one or more control signals are input such that both NLEs receive a control signal at a predetermined time after the first control signal is received by one of the NLEs. Only data signals passing through the first NLE during the switching window are output on the output port. Since both NLEs receive a second control signal at the same time, they decay together and thus avoid creation of unintended switching windows. Additionally, in certain embodiments of the present invention, the second control signal can be input on the data port or the output port, eliminating the need for a separate port for the second control signal as required by certain known TOADs.

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.
