    摘要： In one embodiment, line cards of packet switching or other network devices are configured for terminating pseudowires. Typically, this includes multiple line cards being configured for terminating a same pseudowire, which allows the corresponding pseudowire traffic to be received by any one of these multiple line cards. Each of these pseudowire-terminating line cards is typically configured to apply one or more features to a pseudowire packet. Examples of these features include, but are not limited to: Access Control List, Quality of Service, Netflow, and Lawful Intercept. For a received packet to be sent out one of these pseudowires, a two-stage lookup operation can be used to first identify the pseudowire over which to forward the packet; and a second lookup operation based on the pseudowire to identify forwarding information corresponding to a path through a network over which a corresponding pseudowire is configured.

    摘要： A device for optical space switching in optical networks. The optical device comprises a broad area optical waveguide section having a number of electrodes extending over at least a portion of the length of the broad area optical waveguide section. The application of an electrical signal to an electrode causes a local change in effective refractive index of the broad area optical waveguide section, thereby causing light preferentially to propagate along a predetermined path in dependence on the configuration of the electrode. In particular the broad area waveguide device is implemented in indium phosphide (InP).Also described is a method for waveguiding in the optical device.

    摘要： There is provided a semiconductor laser comprising a gain section and an adjacent Bragg section, wherein output laser light is emitted via a facet at an interface between air and the gain section, the Bragg section comprising a distributed reflecting structure having a length substantially greater than required to ensure single longitudinal mode operation of the laser in which the side-mode suppression ratio (SMSR) is 35 dB or more, thereby in use substantially suppressing optical feedback from a facet at an interface between the Bragg section and air, and wherein an interface between the Bragg section and the gain section is quantum well intermixed, thereby rendering the interface substantially anti-reflecting at the wavelength of the laser.

    摘要： A wavelength locked tunable laser source comprising a tunable laser source, an optical reference source characterized by a frequency spectrum with two combs of discrete components of different spacing, an optical mixing device and feedback control circuitry. An optical output of the laser source is heterodyned with an output of the optical reference source at the optical mixing device to produce an electrical signal in dependence on a difference beat frequency of the two optical outputs, the feedback control circuitry being operative to process the electrical signal to provide a feedback signal which is used to tune the wavelength of the laser source so as to minimize the beat frequency and thereby substantially lock the wavelength of the laser source to a wavelength in the spectrum of the optical reference source. The use of an optical reference source with a spectrum comprising two frequency combs provides a mechanism for determining the absolute frequency to which the laser has been locked.

    摘要： A toaster for heating both a frankfurter and a frankfurter bun is disclosed. The toaster has a frankfurter heating chamber having associated first heating elements for heating at least two opposed surfaces of a frankfurter placed in said frankfurter heating chamber and at least one bun heating chamber having an associated second heating element for heating at least one surface of a bun placed in said bun heating chamber. The toaster includes an elevator having a first portion for supporting the frankfurter in the frankfurter heating chamber and a second portion for supporting the bun in the bun heating chamber. A connecting means connects the first portion to said second portion and permits a limited amount of play between said first and second portion. In one embodiment the connecting means includes a generally upside down U-shaped link bar. The first portion circumferentially restrains the frankfurter for at least a lower half of the frankfurter while simultaneously allowing radiant heat from said first element means to impinge on said restrained lower half of said frankfurter. A means for raising and lowering the elevator in the toaster is also disclosed. In one embodiment the elevator may be removable from said toaster to allow cleaning and the like.
