  • Apparatus and method for switching an optical path
    Patent number: 6678438
    Abstract: An apparatus and method for switching one or more optical paths comprises one or more inputs and one or more outputs arranged with one or more free-space optical paths formed therebetween, and one or more prisms movable to the free-space optical paths being inserted into or removed from the free-space optical paths to control the propagation paths of one or more light beams between the inputs and outputs. When the prism is inserted into the free-space optical path, a switched optical path between the inputs and outputs is formed to direct the light beam with two refraction and one total reflection by the prism. When the prism is removed from the free-space optical path, the light beam propagates along the free-space optical path.
