  • Publication number: 20020067535
    Abstract: A system for performing real time optical comparisons using an optical correlator permits comparing a sampled image to a wide variety of reference images through the utilization of a multiple quantum well spatial light modulator which is utilized to rapidly present a large number of reference images for correlation. The utilization of the multiple quantum well spatial light modulator as the spatial light modulator in a van der Lugt image correlator in combination with a spectrometer permits optical comparisons at 300,000 frames per second versus 10,000 frames per second, the best case for liquid crystal based spatial light modulators.

  • Publication number: 20020003640
    Abstract: An optical transmission device configured as a central node, wherein each central node has dedicated pixels for receiving data and transmitting optical data so destination addressing is not required. The network is configured such that transmission on any particular receiver reserved pixels results in data being sent to a predetermined node. In particular, the star topology is configured as a receiver reserved scheme. The device is formed by constructing central node of transmitters and receivers that are attached to a silicon substrate with a processing means, and the optical interface to the transmitters and detectors on the central node establish a one-to-one correspondence with an individual fiber optic cable. The fiber optic cables are reconfigurable to different topologies or interconnections as each fiber optic cable has a known destination on the central node. Various topologies are possible using a star node as the building block.

  • Patent number: 6316286
    Abstract: A method of equalizing device heights on a chip includes providing on a first chip an array of first devices having a predetermined height including dummy devices with bonding bumps; engaging the bonding bumps on the first chip with those on the second chip; removing the dummy devices to create holes containing the double bumps previously associated with the dummy devices; providing on a third chip an array of second devices having a lower height than the first devices with bonding bumps which match those in the holes; and bump bonding the third chip to the second chip with the second devices in the holes and the bonding bumps on the second devices combining with the multiple bumps in the holes to equalize the height of the first and second devices.

  • Publication number: 20010030924
    Abstract: A method and apparatus utilizing a multiple quantum well modulator/emitter/detector pixel in a bilinear array permits reading or writing to an optical disc in parallel such that information may either be written to or read from an optical disc within one revolution of the optical disc. Thus while existing DVD and CDROM systems operate by sensing the contents of a spiral track, parallel readout afforded by the multiple quantum well modulator/emitter/detector provides as much as 1,000:1 advantage over single detector systems, with the biasing of the modulator/emitter/detector device determining whether the device is an emitter, detector or modulator. The co-location of the modulator/emitter/detector in a single device permits arranging devices in a linear array which is disposed over the optical disc for the parallel read/write functions.

  • Publication number: 20010030782
    Abstract: In a semiconductor device comprising photo-transceiver arrays constructed on silicon substrates with underlying supporting CMOS circuitry in the substrate interfacing with a source of software control, a method is provided for mapping and reconfiguring the global data transfer channel map of optical interconnect lines and intra-nodal routing links. An initial mapping procedure identifies all possible connections. The silicon circuitry provides for sensing optical connections and light levels, for testing or sensing of routing links, and for controlling gain and power, as well as forming and reforming routing links between detectors and emitters. A rule-based routing, mapping and re-mapping scheme, utilizing over-sampling techniques and effectuated by the silicon circuitry and software, accommodates limited misalignment of mating photo-arrays, faults occurring in data transmission channels after the initial mapping, and provides additional security, performance and power management capabilities.

  • Patent number: 5909303
    Abstract: A reversible and conservative photon routing switch is implemented as a room temperature, optical, vertical cavity X-gate (also sometimes known as a Fredkin gate). Such gates are primitive structures into which all logic functions can be decomposed. The construction of the device makes it uniquely suited to dense packed arrays of optoelectronic components for optical routing and logic. In one of the switching states, light incident on the device from either side of the wafer will pass through the device (the device is bi-directionally transmissive). In the other switching state, light incident from either side of the wafer will be reflected. Switching can be performed using either electrical or optical control. Thus incident photons are either routed through the device or reflected from the device.
