Abstract
The invention provides an optical switch having an input port for launching a beam of light into the optical switch, at least two output ports, each output port for selectively receiving a beam of light, an ATO element having optical power for providing an angle to offset transformation, and beam directing means for selectively directing a beam of light from the input port to a selected one of the at least two output ports along an optical path via the ATO element. The ATO element is a lens or a mirror.
Claims30
An optical switch comprising:
- (a) an input port for launching a beam of light into the optical switch;
- (b) at least two output ports, each output port for selectively receiving the beam of light;
- (c) an ATO element having optical power for providing an angle to offset transformation of the beam of light;
- and
- (d) beam directing means for selectively directing the beam of light from the input port to a selected one of the at least two output ports along an optical path via the ATO element.
An optical switch comprising:
- (a) an input port for launching a beam of light into the optical switch;
- (b) at least two output ports, each output port for selectively receiving the beam of light;
- (c) an ATO element having optical power and for providing an angle to offset transformation of the beam of light;
- and
- (d) beam directing means for selectively directing the beam of light from the input port to a selected one of the at least two output ports along an optical path via the ATO element, said beam directing means being disposed near or at a focal plane of the ATO element.
An optical switch comprising an array of controllable deflecting elements for selectively switching a beam of light from an input port to a predetermined one of at least two output ports, and an ATO element optically coupled with the array of controllable deflecting elements for providing an angle to offset transformation of the beam of light, said array of controllable deflecting elements being disposed near or at a focal plane of the ATO element, and wherein a switching of the beam of light is performed along an optical path via the ATO element.
