  • Publication number: 20080118201
    Abstract: A photonic interconnect method avoids high capacitance electric interconnects by using optical signals to communicate data between devices. The method can provide massively parallel information output by mapping logical addresses to frequency bands, so that modulation of a selected frequency band can encode information for a specific location corresponding to the logical address. Wavelength-specific directional couplers, modulators, and detectors, which can be fabricated at defects in a photonic bandgap crystal, can be employed for the photonic interconnect method. The interconnect method can be used for both classical and quantum information processing.

  • Publication number: 20080090318
    Abstract: Embodiments of the invention provide a method and an apparatus for forming a photodiode. One embodiment provides a thin dielectric layer sandwiched between two metallic plates (electrodes), one or both of which are periodically patterned in one or two dimensions. The effect of the pattern is to couple incident light within some range of wavelength and/or incidence angles to surface excitations of the metal surface called surface plasmons, enhancing the electric field near the surface and resulting in dramatically increased photo-absorption and carrier generation in the dielectric layer.

  • Patent number: 7352941
    Abstract: An electromagnetic resonance device includes an input reflector, an output reflector, and a negative index material (NIM) disposed between the input reflector and the output reflector. The input reflector and output reflector are configured to be reflective to radiation having a wavelength of interest. The NIM is configured to have a negative refraction at the wavelength of interest. A first radiation is reflected by the input reflector toward the first surface of the NIM, passes through the NIM, and is focused on the output reflector as a second radiation. The second radiation is reflected by the output reflector toward the second surface of the NIM, passes through the NIM, and is focused on the input reflector as the first radiation. A gain medium may be included to amplify the first radiation and the second radiation to generate a laser radiation.

In one embodiment, a quantum random number generator includes an input state generator that generates a first optical quantum system and a second optical quantum system in an entangled state, a detector that measures the state of the first optical quantum system and the state of the second optical quantum system, and a system control that evaluates a result obtained from measuring the state of the first optical quantum system and state of the second optical quantum system to determine whether or not to append a number associated with the result to the sequence of random numbers. The quantum random number generator also include state controllers, located between the input state generator and the detector, that are operationally controlled by the system control to maintain the entangled state, based on results obtained from previous measurements performed on the first and second optical quantum systems.

  • Publication number: 20070250280
    Abstract: Various embodiments of the present invention are directed to methods for determining a phase shift acquired by an entangled N-qubit system represented by a NOON state. In one embodiment, a probe electromagnetic field is coupled with each qubit system. The phase shift acquired by the qubit systems is transferred to the probe electromagnetic field by transforming each qubit-system state into a linear superposition of qubit basis states. An intensity measurement is performed on the probe electromagnetic field in order to obtain a corresponding measurement result. A counter associated with a measurement-result interval is incremented, based on the measurement result falling within the measurement-result interval. A frequency distribution is produced by normalizing the counter associated with each measurement-result interval for a number of trials.

  • Publication number: 20070154129
    Abstract: A sensor includes traps that are adjacent to a waveguide and capable of holding a contaminant for an interaction with an evanescent field surrounding the waveguide. When held in a trap, a particle of the contaminant, which may be an atom, a molecule, a virus, or a microbe, scatters light from the waveguide, and the scattered light can be measured to detect the presence or concentration of the contaminant. Holding of the particles permits sensing of the contaminant in a gas where movement of the particles might otherwise be too fast to permit measurement of the interaction with the evanescent field. The waveguide, a lighting system for the waveguide, a photosensor, and a communications interface can all be fabricated on a semiconductor die to permit fabrication of an autonomous nanosensor capable of suspension in the air or a gas being sensed.
