Acousto-optical switch for fiber optic lines

摘要

An optical switch for coupling a trunk optic fiber to a selected branch optic fiber is disclosed. The switch includes one or two optically active elements which are capable of being configured to have a different diffraction angle. The elements are configured so that an optical signal emitted from the trunk fiber is directed into the selected branch fiber. The switch may also operate in reverse to couple a signal from the branch fiber into the trunk fiber.
