Abstract
An optical time shifter and routing system having high efficiency switched gratings to form optical time delay and routing networks. This system also includes a unique passive noise suppression device that can be used in multiple channel optical systems such as time shifters and routers to increase channel isolation and reduce crosstalk. The latter noise suppression devices are applicable broadly to the free-space time shifters as well as to other time shifters.
