ABSTRACT:
An optical switching device for use with optical fibers. The fibers are positioned on input and output sides of the switch, with each fiber terminated by a lens for collimating incident light emitted from an input optical fiber. At least one transparent dielectric plate, with a uniform refractive index, is disposed between lenses associated with the input and output sides of the switch. The transparent plate changes the optical transmission path of the collimated light beam when present in a light transmission path. When the transparent dielectric plate is driven into the light transmission path, the optical axis is switched from one to a different output optical fiber.
