摘要： An n-channel optical interconnect is suitable for use as a high speed, low latency interconnect at a backplane of a parallel processing computer. The interconnect uses spectral slicing to address the output of the processor to one or more other processors. Each processor has an optical receiver and n optical sources that each produce the same spectrum. The light output of the sources is directed to a wavelength division multiplexer (WDM) that produces an optical output signal in one or more portions of the spectrum. A selected portion is produced by energizing a selected one of the n optical sources. Each portion is associated with a single addressee processor. A passive star coupler combines all of the outputs of all of the WDM's. A wavelength division demultiplexer (WDDM) separates this composite signal back into the spectral portions. Electronic gating logic enables the appropriate source or sources at each transmitting processor. Control logic monitors transmissions from the star coupler to prevent collisions.

摘要： A node for a fast packet-switching network in optical-electrical technology comprises an optical switching matrix and electrical control equipment which processes the signalling and the information packet headers. More particularly, the control equipment updates the label and, depending on such a label, searches for the routing through the node. A centralized node controller processes the signalling, while a distributed processing system processes the packet headers and routes the packets through the network. For all communications in progress, the distributed processing system periodically forwards routing requests to an electrical self-routing switching matrix associated with the optical matrix. When a connection path has been found between an input and an output of the electrical matrix, the same path is reproduced in the optical matrix and the packets are transferred to the node output through the optical matrix.

摘要： An optical switching system, wherein the input channels carrying packetized data are switched one-by-one at high bit rate to output channels through an optical switching network. The packets of a generic input channel are time compressed, converted into optical signals and, at suitable instants, sent to an optical switching network to be switched to the desired output channel, they are then reconverted into electrical signals and expanded to their original duration. A centralized processor controls the channel switching through the switching network by means of a driving circuit.

摘要： A method of establishing a data connection between terminal switching nodes in a network and switching nodes for implementing the method. The method involves switching nodes participating in a network layer wavelength routing (WR) protocol to determine the next hop switching node for every possible combination of terminal nodes based on the network topology. The method also involves the switching nodes participating in a network layer wavelength distribution (ND) once the data connection is to be established. The WR protocol determines the path used through the network, while the WD protocol assigns wavelengths on each link between switching nodes. The wavelengths may be different on different optical links. The switching nodes include wavelength converters with an optical switch or optoelectronic converters with a digital electronic switch. A digital electronic switch can also provide signal reformatting. Advantages of using potentially different wavelengths along various segments of a single end-to-end connection yields increased wavelength efficiency.

摘要： A wavelength converter includes first silicon waveguides and second silicon waveguides intersecting the first silicon waveguides to form an arrayed waveguide. The arrayed waveguide receives optical data signals at the same wavelength at a first input and optical pump signals at different wavelengths at a second input. Microring resonators evanescently couple different ones of the first silicon waveguides to different ones of the second silicon waveguides. Each microring resonator is tuned to the wavelength of the optical data signals or one of the wavelengths of the optical pump signals, so that different combinations of the optical data signals and the optical pump signals are provided at an output of the arrayed waveguide. A non-linear optical media converts the wavelength of each combined optical signal at the output of the arrayed waveguide to yield wavelength converted signals each having a new dedicated wavelength.
