  • Patent number: 8610994
    Abstract: Optical devices, phased array systems and methods of phase-shifting an input signal are provided. An optical device includes a microresonator and a waveguide for receiving an input optical signal. The waveguide includes a segment coupled to the microresonator with a coupling coefficient such that the waveguide is overcoupled to the microresonator. The microresonator receives the input optical signal via the waveguide and phase-shifts the input optical signal to form an output optical signal. The output optical signal is coupled into the waveguide via the microresonator and transmitted by the waveguide. At an operating point of the optical device, the coupling coefficient is selected to reduce a change in an amplitude of the output optical signal and to increase a change in a phase of the output optical signal, relative to the input optical signal.

  • Patent number: 7667200
    Abstract: A thermal microphotonic sensor is disclosed for detecting infrared radiation using heat generated by the infrared radiation to shift the resonant frequency of an optical resonator (e.g. a ring resonator) to which the heat is coupled. The shift in the resonant frequency can be determined from light in an optical waveguide which is evanescently coupled to the optical resonator. An infrared absorber can be provided on the optical waveguide either as a coating or as a plate to aid in absorption of the infrared radiation. In some cases, a vertical resonant cavity can be formed about the infrared absorber to further increase the absorption of the infrared radiation. The sensor can be formed as a single device, or as an array for imaging the infrared radiation.

  • Patent number: 7254335
    Abstract: A module that includes both an “add-in”/“drop-out” pair of ports and a “drop-in”/“add-out” pair of ports comprises an arrangement of elements that combines an optical signal having a chosen wavelength with an optical signal applied at the “add-in” port, and outputs the combined signal at the “add-out port.” Concurrently, the module extracts an optical signal with the same wavelength from an optical signal applied at the “drop-in” port signal, yielding an optical signal at the “drop-out” port that is missing that same wavelength. When the amount of information that needs to be sent from a first network node to a second, remote, node, is greater than that which a single wavelength can handle, a plurality of the above-described modules are interconnected within the first node by optically coupling the “add” ports in a “daisy chain” fashion and the “drop” ports in a “daisy chain” fashion, with each module operating at a different wavelength.

  • Patent number: 6396970
    Abstract: A switch, of the crossbar type, in which no clock recovery is undertaken. Multiple optical fibers deliver input signals to a single semiconductor die. The die contains circuitry which selectively connects each input fiber to a respective output fiber, which carries the signals off the die, to their destinations. The communication is asynchronous: no continuous clock signal accompanies the incoming data. However, periodic sequences of clock signals accompany the incoming data, and are used by circuitry on the die in “clock recovery” routines, to generate local clock signals. The invention eliminates the need for local clock recovery: the incoming signals are routed through the die to outgoing fibers, without generation of a local clock signal on the die.

  • Publication number: 20020037018
    Abstract: An apparatus and method for enabling the transport of a higher line rate time-multiplexed data signals (e.g., Ethernet at 10 Gb/s) at a lower line rate (e.g., SONET OC-192) and for regenerating the higher line rate time-multiplexed data signals at the receiving end. At a transmitter end, a data stream compression apparatus removes a predetermined portion of non-unique, invariant content of the higher line rate data stream thereby generating the lower line rate data stream which is transmitted over a communication link to the receiver end. At the receiver end, a data stream expansion apparatus adds back the missing predetermined portion of non-unique, invariant content to the lower line rate data stream thereby regenerating the higher line rate data stream. A data compression multiplexer apparatus is formed by combining a plurality of the data stream compression apparatuses with a data multiplexer.

  • Patent number: 5448393
    Abstract: An optical receiver apparatus and method for receiving optical signals and for generating output signals is disclosed. In particular, a photoconductor is illuminated with a preset beam before an input beam is incident on a detector to reset an input FET. An optical receiver according to the invention controls the voltage swings and the allowed voltages at the input stage, and can be monolithically integrated to allow uniform operation across a semiconductor chip and between circuits on different chips.

  • Patent number: 5343032
    Abstract: An optical receiver, e.g., receiver 10 (FIG. 1), has differential optical input beams and generates an electrical output. The voltage at an electrical node between series-connected optical detector diodes is clamped within a predefined voltage range by series-connected clamping diodes, to prevent the voltage from increasing when consecutive logic one optical input beams are received. Variable bandwidth and low energy dissipation are achieved since the resistors of high input impedance and transimpedance receivers are not required. A second optical receiver, e.g., receiver 20 (FIG. 2) is a monolithic, diode-clamped S-SEED with complementary optical input beams and complementary optical output beams.

  • Patent number: 5258978
    Abstract: A multi-stage network which achieves the same overall connectivity as known networks but where individual switching nodes have no input selectivity and no output selectivity. Each node is enabled or disabled to control communication therethrough in response to a single control signal. The functionality of a switching network is achieved by controlling which nodes are enabled rather than specifying connections of particular node inputs and outputs to be effected by the nodes. In a photonic network embodiment, each network node is implemented using a single symmetric self electro-optic effect device (S-SEED).

  • Patent number: 5172259
    Abstract: A network comprising a plurality of successively interconnected node stages where each node has an associated data connection state and includes a control element, significantly implemented as part of the node itself, for controlling the data connection state of at least one node of the following stage. The network is well suited for optical implementation and is controlled by shifting bits into the network for storage by the control elements rather than relying on spatial light modulators.

  • Patent number: 5153757
    Abstract: A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.
