Abstract: A packet router uses high-speed superconducting circuits to process incoming data bits, read the packet header, and pass the packet header to a non-superconducting semiconductor controller. The controller determines the appropriate destination for the packet, and sends corresponding control signals to a superconducting router. The superconducting router routes each packet to its intended destination based on these control signals.

Abstract: A narrowband laser source includes an optical fiber section including a core centered on a longitudinal axis and a cladding surounding the core, and having a grating region embedded in the core. The grating region includes a multitude of Bragg grating elements extending with a substantially equal longitudinal spacing substantially normal to the longitudinal axis for the grating region to significantly reduce the amount of light passing therethrough when the frequency of such light is in a predetermined narrow range around and including a predetermined center frequency, to an extent proportionate to the deviation of such frequency from the center frequency. A portion of the light emitted by a laser at a frequency dependent on the amount of electric energy applied to the laser is supplied into the core of the fiber section for propagation toward the grating region.

Abstract: A temperature compensated embedded grating optical waveguide light filtering device includes an optical fiber having an elongated core in which light is guided toward a core portion of a predetermined limited length that has embedded therein a multitude of grating elements extending with a substantially equal longitudinal spacing substantially normal to the longitudinal axis and collectively constituting a grating that reflects, of the light propagating in the path toward and reaching the grating elements, that of a wavelength within a narrow range about a central wavelength determined by the spacing of the grating elements and by the index of refraction of the material of the core as influenced by the temperature of and longitudinal strains applied to the grating, back into the path for longitudinal propagation therein opposite to the original propagation direction.

Abstract: A demagnetization compensated magnetostrictive actuator includes a magnetostrictive displacement element and an excitation element responsive to an external signal for providing an applied magnetic field; it further includes a magnetic yoke configuration that encloses both the displacement and excitation elements, for providing a low magnetic reluctance path for the magnetic flux provided by the applied magnetic field.

Abstract: An optical fiber transducer system employs a single optical fiber that carries an optical carrier signal to a remote transducer location and also carries a multiplexed multichannel signal, each channel having a characteristic delay and a binary amplitude value, to a receiving unit, where each channel of a set of reference signals having a corresponding characteristic delay interferes with the multiplexed signal to separate a channel signal that is envelope detected.

Abstract: A demagnetization compensated deformable magnetostrictive mirror comprises an array of magnetostrictive actuators that are positioned between a continuous low magnetic reluctance yoke. A faceplate having a reflective surface and a substrate are both fabricated to receive the magnetic yoke's outer surface and are affixed thereto to be approximately perpendicular to the mirror's deformation axis.

Abstract: A focused optical input signal is applied to an optically absorbent wall portion of a supply nozzle 40 in a fluidic device to cause boundary layer separation of flow therein. The boundary layer separation turns the flow to achieve a desired output from the device.

Abstract: A piezoelectric fluidic power supply comprises two piezoelectric devices (30, 31) connected both electrically and fluidically. Each device has a movable piston end (26, 27) which extends into a corresponding fluid chamber (23, 24), each piston variably restricting fluid flow through its corresponding fluid chamber. The first piezoelectric device, responding to fluid pressure changes, acts as a power generating device (30). The second piezoelectric device, responding to the electric power flow of the power generating device acts as a cycle control device (31) by modulating the fluid pressure on the first device. This arrangement effects a cycling of the two pistons, consequently generating electric power. Such an arrangement provides integral fluidic feedback control with inherent impedance matching between the fluid and the piezoelectric components.
