摘要： A system includes a transmitter configured to output an optical signal. The transmitter includes a seed laser, an optical array including a plurality of array elements, and a plurality of phase shifters in a multi-layer arrangement. The multi-layer arrangement includes a plurality of layers between the seed laser and the optical array, wherein a first layer of the plurality of layers transmits light to a second layer of the plurality of layers. The first layer has fewer phase shifters than the second layer. The multi-layer arrangement also includes a plurality of branches wherein each branch includes a phase shifter from each of the plurality of layers connected in series between the seed laser and one of the plurality of array elements. Each phase shifter is configured to shift the optical signal incrementally to amass a total phase shift for each of the plurality of array elements.

摘要： An input device for a multiple wavelength band optical switch comprising: an optical demultiplexer configured to receive light and disperse the received light along a dispersion axis; and a light director configured to direct light in a first wavelength band to the optical demultiplexer at a first angle of incidence and to direct light in a second wavelength band to the optical demultiplexer at a second angle of incidence, the second angle of incidence being different from the first: wherein the difference between the first and second angles of incidence causes the demultiplexer to output dispersed spectra of light corresponding to the first and second bands such that the dispersed spectrum corresponding to the first band is overlapped along the dispersion axis and separated along a switch axis relative to the dispersed spectrum corresponding to the second wavelength band, the switch axis being perpendicular to the dispersion axis.

摘要： Network devices and associated methods are provided for synchronization in an optically switched network. The network device includes one or more ports in communication with a plurality of devices via an optical switch. The one or more ports receive a master clock signal having a first frequency from a first device of the plurality of devices. The network device includes a local clock in communication with the one or more ports and operating at a second frequency. The network device includes a synchronization manager in communication with the one or more ports and the local clock and configured to be enabled and disabled. When the synchronization manager is enabled, it receives the master clock signal via the one or more ports and transmits an instruction to the local clock to operate at the first frequency.

摘要： A registration signal sending and reception method, an optical transmission apparatus, an optical reception apparatus, and a system are provided. The registration signal sending method includes generating registration information and loading, by using a transmission enable port, the registration information into a spontaneous-emission optical signal generated by a laser to generate a registration signal. The registration signal, which is an optical signal carrying the registration information, is loaded into the laser by using the transmission enable port to generate the registration signal so as to prevent a silence window from being opened in a registration process, thereby reducing uplink delay jitter, and achieving low-cost transmission of a registration signal.
