Radiation switching arrangement with moving deflecting element.

摘要

A three or four-port electromagnetic radiation signal beam switching arrangement (FIG. 2, FIG. 3), such as for simple optical re-routing or for Local Area Network (LAN) loop switching, is achieved with a moving deflecting element (M) having a planar deflecting surface (MS1) that is constrained to move parallel to itself, into and out of the signal beam. The arrangement can be fabricated in a silicon optical workbench technology.
