    摘要： A method for an electronic device is provided for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in the electronic device. The method emits extraneous randomized light emissions in substantial close proximity to the transistors to hide a pattern of light emissions emitted from the transistors. As one feature, the device can include a source of randomized light emissions in substantial close proximity to the transistors to hide a pattern of the emitted light from the transistors in randomized light emissions emitted by the source. As a second feature, the device can emit the randomized light emissions by randomly delaying an electrical signal that is electrically coupled to the transistors and, in response to the randomly delayed electrical signal, the transistors randomly emitting light emissions thereby hiding a separate pattern of light emission emitted from the transistors.

    摘要： An integrated circuit chip (IC) is equipped with a device for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in a circuit located in the IC. The device emits extraneous randomized light emissions in substantial close proximity to the transistors to hide a pattern of light emissions emitted from the transistors. As one feature, the device can include a source of randomized light emissions in substantial close proximity to the transistors to hide a pattern of the emitted light from the transistors in randomized light emissions emitted by the source. As a second feature, the device can emit the randomized light emissions by randomly delaying an electrical signal that is electrically coupled to the transistors and, in response to the randomly delayed electrical signal, the transistors randomly emitting light emissions thereby hiding a separate pattern of light emission emitted from the transistors.

    摘要： A system for time-correlated photon counting. The system uses one or more photon detectors to produce electrical pulses corresponding to photons read from a target. The system uses a discriminator with a first input coupled to a trigger output from a pulsed optical source and a second input for receiving the electrical pulses. A time-to-pulse height converter is used for producing a series of difference signals each with a respective maxima and whose magnitude is related to the time difference between the trigger output and the electrical pulses. In addition, the system employs a pulse shaping electronic circuit for receiving pulsed electrical output and producing a series of one or more characteristic signals. An A/D converter with a first input receives the difference signals and a second input receives part of the characteristic signals. The A/D converter produces a first series of digital signals representing the difference signals and a second series of digital signals representing the characteristics signals. The results of the A/D converter are feed to a multichannel analyzer for time-shifting the first series of digital signals based on at the second series of digital signals so that the maxima for any given difference signals occurs at the same time as the maxima for at least one other part of the series of the difference signals.

    摘要： An apparatus is described for obtaining single frequency laser operation in a coupled waveguide configuration without using a diffraction grating. More specifically, this invention is a laser structure for oscillating light in single longitudinal mode. This structure has a pair of coupled but dissimilar waveguides that are collinear with each other and separated by a mirror in contact with each of the guides. The length of the waveguides are adjusted so that frequency selective coupling between the waveguides can discriminate between wavelengths corresponding to different longitudinal modes.

    摘要： Picosecond response photoconductors and photoresponsive elements can be provided that retain high carrier mobility and yet have short lifetime by providing on a crystal mismatched substrate a textured layer of domain regions wherein the domain size is such that the lifetime is proportional to the square of the size divided by the diffusion coefficient of the semiconductor material. The crystalline orientation in the domains with respect to the substrate is maintained. An embodiment is an approximately 0.1 micron thick textured layer of GaAs grown on a hexagonal monocrystalline Al.sub.2 O.sub.3 having domains approximately 1.0 micron with a carrier lifetime about 5 picoseconds and a carrier mobility of about 80 cm.sup.2 volt.sup.-1 sec.sup.-1.

    摘要： An integrated circuit and method are provided for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in the integrated circuit. The method prevents, in an integrated circuit, a pattern of light emitted from at least one active device in the integrated circuit from being detected external to the integrated circuit by fading the light emitted from the at least one active device in the integrated circuit and that is emitted external to the integrated circuit. Bright light emission emitted in substantial close proximity to the at least one active device in the integrated circuit, and emitted external to the integrated circuit, fades a pattern of light emission emitted from the at least one active device.
