摘要： This invention relates to opto-electronic systems using semiconductor lasers driven by feedback control circuits that control the laser's optical phase and frequency. Feedback control provides a means for coherent phased laser array operation and reduced phase noise. Systems and methods to coherently combine a multiplicity of lasers driven to provide high power coherent outputs with tailored spectral and wavefront characteristics are disclosed. Systems of improving the phase noise characteristics of one or more semiconductor lasers are further disclosed.

摘要： This invention discloses highly scalable and modular automated optical cross connect switch devices which exhibit low loss and scalability to high port counts. In particular, a device for the programmable interconnection of large numbers of optical fibers (100's-1000's) is provided, whereby a two-dimensional array of fiber optic connections is mapped in an ordered and rule-based fashion into a one-dimensional array with tensioned fiber optic circuit elements tracing substantially straight lines there between. Fiber optic elements are terminated in a stacked arrangement of flexible fiber optic circuit elements with a capacity to retain excess fiber lengths while maintaining an adequate bend radius. The combination of these elements partitions the switch volume into multiple independent, non- interfering zones, which retain their independence for arbitrary and unlimited numbers of reconfigurations. The separation into spaced-apart zones provides clearance for one or more robotic actuators to enter the free volume substantially adjacent to the two-dimensional array of connectors and mechanically reconfigure connectors without interrupting other circuits.
