摘要： An optical line card includes a plurality of coherent receivers and a plurality of optical modulators. The coherent receivers are each configured to receive a corresponding channel of a received optical superchannel. The optical modulators are each configured transmit a corresponding channel of a transmitted optical superchannel. Each of a plurality of optical splitters is configured to receive a corresponding one of a plurality of unmodulated optical signals from an optical source external to the line card. Each splitter directs a first portion of light received by that splitter to a corresponding one of the coherent receivers, and a second portion of light received by that splitter to a corresponding one of said optical modulators.

摘要： A WDM device having a controller that individually controls the operating parameters of tunable lasers and the temperatures of an optical multiplexer and etalon. The device employs a spectral analyzer to measure the spectral composition of the optical output signal produced by the device. Based on the analyses of the measured spectral composition, the controller sets the temperatures of the tunable lasers, optical multiplexer, and optical etalon to values that cause: (i) middle frequencies of transmission bands of the optical multiplexer to be spectrally aligned with the corresponding frequencies of the specified frequency grid, (ii) each laser line to be properly positioned within the corresponding transmission band, and (iii) transmission resonances of the optical etalon to be properly positioned with respect to the laser lines.

摘要： In one embodiment, a three-stage scalable hybrid switch fabric has an input stage with one or more electronic input crossbar switches, a middle stage, and an output stage with one or more electronic output crossbar switches. The middle stage has (1) tunable optical transmitters that convert electrical signals received from the input stage into optical signals having selectable wavelengths, (2) one or more passive, wavelength-dependent optical routers that route the optical signals received from the transmitters at input nodes to output nodes, each output node determined by the wavelength of the optical signal and possibly by the input node at which the optical signal is applied, and (3) optical receivers that convert the routed optical signals into electrical signals provided to the output stage. Each scaling increment includes (i) an input crossbar switch and its corresponding optical transmitters and (ii) an output crossbar switch and its corresponding optical receivers.

摘要： A dispersion compensator having relatively uniform transmission characteristics over the bandwidth of a communication channel. The compensator is designed to process an optical signal corresponding to the communication channel by decomposing that signal into spectral components, routing different components along different optical paths that impart relative delays between the components, and recombining the delayed components spatially and directionally to generate a processed optical signal with reduced chromatic dispersion. In one embodiment, the compensator is a waveguide circuit that includes four diffraction gratings operating in transmission and optically coupled to a tunable lens array, in which different tunable lenses receive light corresponding to different communication channels. For each channel, a desired group delay value is produced by selecting magnification strength of the corresponding tunable lens.
