摘要： A device that provides reconfigurable optical interconnections of multipleata channels that have applications in highly parallel computers. The device utilizes an array of optical switches which direct a set of optical beams toward any one of a selection of holograms and each hologram when selected deflects the input beams toward a detector.

摘要： A pulsed source of laser light (10) includes a diffraction grating (20) that splits light received from a laser output mirror (12) into a plurality of paths that lead to respective laser gain cells (14.sub.1, 14.sub.2, . . ., 14.sub.n). The gain cells individually amplify light components of different respective wavelengths and reflect them back to the diffraction grating (20), which reassembles them into a single beam for transmission to the laser output mirror (12). A mode locker (24), preferably in the form of a saturable absorber, locks the output components into equally spaced frequencies so that the sum of the individual continuous components will be a pulsed signal.
