    摘要： An avalanche photodiode detector is provided with a substrate including an array of avalanche photodiodes. An optical interface surface of the substrate is arranged for accepting external input radiation. There is provided at least one cross-talk blocking layer of material including apertures positioned to allow external input radiation to reach photodiodes and including material regions positioned for attenuating radiation in the substrate that is produced by photodiodes in the array. Alternatively at least one cross-talk blocking layer of material is disposed on the optical interface surface of the substrate to allow external input radiation to reach photodiodes and attenuate radiation in the substrate that is produced by photodiodes in the array. At least one cross-talk filter layer of material can be disposed in the substrate adjacent to the photodiode structures, including a material that absorbs radiation in the substrate that is produced by photodiodes in the array.

    摘要： A transceiver for transmitting and receiving high frequency radiation is described. The transceiver includes a first light source that generates radiation at a first frequency and a second light source that generates radiation at a second frequency. The first and the second light source have a difference frequency that is approximately equal to the difference between the first and the second frequencies. The transceiver also includes a transmitter that comprises a first photomixer that is optically coupled to the first and the second light source. A first antenna that radiates a signal at the difference frequency is electrically coupled to the first photomixer. The transceiver also includes a receiver that comprises a second antenna positioned to receive the signal radiated by the first antenna. The second antenna generates a time varying voltage in response to the signal. A second photomixer is electrically coupled to the second antenna and optically coupled to the first and the second light source. The second photomixer generates a current signal in response to the time varying voltage generated by the second antenna.

    摘要： Described is a system for wireless energy transfer for person worn peripherals. The system makes use of a technique referred to as strongly-coupled magnetic resonance to transfer energy across a distance without wires and enables efficient transfer of energy over distances of 10 to 18 cm or more. The system comprises a resonant power source, which could be embedded in a person's equipment vest or backpack receiving power from a central battery pack or micro fuel cell, and a resonant power capture unit which could be integrated with the helmet or hand held weapon, electronic device, and the like that may be carried or handled by a person.

    摘要： An optical correlator for correlating incident optical signals is described. The correlator comprises a transmission line in close juxtaposition to a photoconductor. The photoconductor may be positioned within the transmission line. The transmission line and the photoconductor may be monolithically integrated on a substrate. The optical correlator has an electrical non-linear response to the incident optical signals that results from a voltage divider formed from the combination of the transmission line and the photoconductor. The electrical non-linear response is proportional to a second-order intensity autocorrelation function g.sup.(2) (.tau.). The response time of the electrical nonlinear response is less than the width of the narrowest pulse of the optical signals and may be less than twenty picoseconds.
