Abstract: A spread spectrum waveform generator has a photonic oscillator and an optical heterodyne synthesizer. The photonic oscillator is a multi-tone optical comb generator for generating a series of RF comb lines on an optical carrier. The optical heterodyne synthesizer includes first and second phase-locked lasers, where the first laser feeds the multi-tone optical comb generator and the second laser is a single tone laser whose output light provides a frequency translation reference. At least one photodetector is provided for heterodyning the frequency translation reference with the optical output of the photonic oscillator to generate a spread spectrum waveform. A receiver pre-processor may be provided to operate on the spread spectrum waveform.

Abstract: A photonic detector, a photonic imaging system and a method of photonic detection employ plasmonic resonant absorption to detect an incident electromagnetic signal. The photonic detector and imaging system include a micro/nanoshell (MNS) structure that supports a surface plasmon and a rectifying junction that rectifies an evanescent electric field of the surface plasmon. The surface plasmon is excited by the incident electromagnetic signal at a plasmonic resonant absorption wavelength of the MNS structure. The method of photonic detection includes providing an MNS structure, exciting a surface plasmon on the MNS structure and rectifying an evanescent electric field of the excited surface plasmon to produce a rectified output signal. The rectified output signal provides detection of the incident electromagnetic signal.

Abstract: In one implementation, a method is provided for frequency tuning of a photonic oscillator. The method includes supplying an optical signal, for example laser light, which is modulated, delayed, and then converted to an electrical signal. The electrical signal is amplified, and used in modulating the optical signal. With this implementation, the frequency of the an output signal of the photonic oscillator is shifted by adjusting a bias voltage of the amplifier. In some implementations, shifting the frequency of the output signal further includes using a frequency lock loop circuit. In some implementations, shifting the frequency of an output signal of the photonic oscillator further comprises adjusting at least one of an phase shifter in series with the amplifier, an optical fiber stretcher, or a bias voltage of a second amplifier.

Abstract: A phase shifter comprises a coarse phase tuning arrangement and a fine phase tuning arrangement. The coarse phase tuning arrangement provides a discrete number of phase shifts. The fine phase tuning arrangement includes a RLC network, having a resistor, an inductor and a capacitor. The fine phase tuning arrangement also comprises an optical arrangement for varying the resistance value of the resistor. This phase shifter is able to obtain broadband, continuous 360° phase shifting also at Gigahertz frequencies. It also allows close to linear phase shift versus frequency resulting in true time delay capability, very low insertion loss and high value of maximum phase adjust.

Abstract: A method for transferring layers containing semiconductor devices and/or circuits to substrates other than those on which these semiconductor devices and/or circuits have been originally fabricated. The method comprises fabricating the semiconductor devices and/or circuits, coating them with a protective layer of photoresist followed by coating with a layer of wax. A special perforated structure is then also wax coated and the waxed surface of the structure is brought into a contact with the waxed surface of photoresist. The original seed substrate is removed and the exposed surface is then coated with adhesive followed by dissolving wax through the openings in the perforated structure and attaching the layer with semiconductor devices and/or circuits to another permanent substrate. As an alternative, a disk-shaped water-soluble structure can be used instead of the perforated structure.

Abstract: A photoconductive substrate is provided to voltage modulate a liquid crystal layer in response to input light. The substrate is partitioned into electrically isolated pixels to eliminate lateral spread of charge carriers therein, and increase the dynamic range of the liquid crystal light valve while preserving resolution. The substrate is partitioned by forming an interconnecting network of deep trenches in a surface thereof, and filling the trenches with an insulating material such as silicon dioxide. The opposite surface of the substrate is etched away to expose the silicon dioxide in the trenches, thereby providing the substrate with partitions which extend completely therethrough between the opposite surfaces.
