    摘要： In a WDM optical communication system that includes a plurality of nodes interconnected by communication links, a node is provided that includes a reconfigurable optical switch having a plurality of input ports and at least one output port. The node also includes a plurality of transmitters that are each coupled to one of the input ports of the optical switch. Each of the transmitters generate an information-bearing optical signal at a different channel wavelength from one another. The reconfigurable optical switch is adaptable to receive at any of the input ports any of the channel wavelengths at which the plurality of transmitters operate and direct the channel wavelengths to the output port. At least one backup transmitter is coupled to one of the input ports of the optical switch. The backup transmitter includes a tunable laser tunable to any of the channel wavelengths at which the plurality of transmitters operate. The reconfigurable optical switch includes at least one wavelength selective element that selects at least one channel wavelength from among any of the channel wavelengths received at any of the input ports. The switch also includes a plurality of optical elements associated with the wavelength selective elements, Each of the optical elements direct one of the selected channel wavelengths selected by the associated wavelength selective element to the output port independently from every other channel wavelength. The selected channel wavelengths directed to the output port are combined on the output port.

    摘要： Aspects of embodiments pertain to beam combining devices for coherent and spectral beam-combining. The coherent beam combining (CBC) device may comprise a monolithic body having an input surface and an output surface. The input surface may be configured to direct a plurality of coherent entering optical beams through an optical pathway inside the monolithic body towards the output surface; and a phase mask configured for combining beams, exiting from the output surface of the monolithic body, to form a single combined output beam. The Spectral beam combining (SBC) device may include a monolithic body configured to direct the entering optical beams through a multi-diffraction optical pathway inside the monolithic body by directing the entering optical beams such as to impinge a diffractive surface thereof at least twice, for combining the entering optical beams into a single multispectral combined output optical beam. Embodiments may also include methods for cascaded beam combining, using multiple combining devices in a network configuration.

    摘要： A system including wavelength multiplexers. In some embodiments, the system includes: a first multiplexing element, having a first plurality of input waveguides, each configured to receive light at a respective wavelength of a first plurality of wavelengths; and a second multiplexing element, having a second plurality of input waveguides, each configured to receive light at a respective wavelength of a second plurality of wavelengths. A wavelength of the second plurality of wavelengths may fall between a first wavelength of the first plurality of wavelengths and a second wavelength of the first plurality of wavelengths.
