Abstract
A one-sided switch for redirecting light between adjacent ports. The switch uses a moveable refractor, in combination with a lens and a stationary reflector, to redirect light from one optical port to another. In a most simple embodiment light is redirected from one output port to another by repositioning the refractor in the optical path of the light and using only a single lens for collimating and focussing the light at the reflector and about the ports, respectively.
