摘要： Spatial modulation representing digital information is imposed on a pump laser beam, and differing modulation representing different digital information is imposed on a second light beam which has a frequency equal to the pump beam less the nonlinear optical Stokes frequency shift. All the digital information on the two beams is logically combined simultaneously in a single waveguide containing the corresponding nonlinear optical (e.g. Brillouin) material with the result of the logical operations recorded on the wavefront of the second light beam.

摘要： A system for optimizing the RF input drive to a TWT amplifier over a frequency band of interest is disclosed. The system includes a microprocessor-based controller, an RF detector for detecting the TWT output, and a variable attenuator for adjusting the input drive to the TWT. The controller comprises an analog-to-digital converter for converting the video detector signals and providing digital RF level signals which are representative of the TWT output power level. Frequency data is also provided to the controller indicating the frequency of the RF exciter signals driving the TWT. The controller is, therefore, provided with frequency and RF level information, and is adapted to control the attenuator to adjust the TWT input drive for optimum TWT output. The system is operable in a calibration mode wherein the controller follows a calibration algorithm to determine the optimum attenuator setting, resulting in the maximum RF output, for each frequency of interest. The optimum attenuator setting is stored in an EEPROM for each drive frequency. The system is further operable in a normal mode wherein the controller sets the attenuator at the predetermined optimum setting for the present exciter frequency.

摘要： Josephson devices are distributed in series in a transmission line structure in which electromagnetic waves are used to synchronize the dynamics of the Josephson devices in order to achieve coherence between the devices. Electromagnetic waves, such as oscillatory traveling waves, standing waves, and solitary waves along the transmission line couple the Josephson devices in a manner such that coherence is achieved for the entire array. The Josephson devices can be tunnel junctions, point contacts, micro bridges, and weak links, and more generally include any such superconductive device which obeys the Josephson equations of voltage and current. The transmission line is any line which controllably supports electromagnetic waves, and can include strip lines located over a ground plane, coaxial lines, etc. A DC bias is supplied to the transmission line, and the ends are terminated in accordance with the type of wave to be propagated along the line. Each Josephson device couples to the electromagnetic wave along the transmission line where many Josephson devices can be in series. Typically, the Josephson devices are spaced closer than the wavelength of the electromagnetic wave, although this is not a necessity. The coherent array can be used for wave generation and detection, amplification, and as a voltage standard.
