| 摘要 |
This invention relates to a method and apparatus for switching an optical signal from one or more input ports to one of a plurality of output ports. A beam is launched into the input port. By controllably switching a switching element, such a liquid/air switch selection can be made selecting a plurality of deflections along a first plane to direct a beam along the first plane to one of a plurality of output locations; the beam is received from one of the plurality of locations and is directed along a second plane intersecting the first plane, to direct the beam to one of the output ports. In a preferred embodiment, the switch includes two prisms each having switching elements at end faces of the prisms.
