An optical routing system and/or switching system having high efficiency switched gratings to the system. This system also includes a unique passive noise suppression device that can be used in multiple channel optical systems to increase channel isolation and reduce crosstalk.

Optical routing/switching systems

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.

Optical time shifter and routing system

A vertical cavity signal suppressor array having a plurality of suppressor elements, each of which incorporate therein an active semiconductor region bounded by reflective elements and a source of current 20 connected thereto. When in operation within a multichannel optical system a preselected signal suppressing element the signal suppressor array is turned 'on' in the selected channel of interest. This is accomplished by either injecting a small current through the reflective elements or by optical pumping, and the desired signal channel is transmitted with little or no loss. All the non-selected channels remain undriven or 'off', that is, a state in which they are strongly absorptive.
