Abstract
An optical switch comprised of an artificial muscle activation material that is adhered longitudinally around an optical channel, such as an optical fiber or group of fibers, to cause the channel to undulate in 2-½ dimensions when the material is activated by a voltage source via electrodes on the surface of the artificial muscle activation material. The material can be applied to the optical channel in a series of longitudinal strips or as a jacket surrounding the channel. When activated by a voltage source, be it a constant source or a variable source varying in amplitude, frequency or polarity, the artificial muscle material bends, causing the optical channel to also bend. The artificial muscle activation material can be formed into an optical channel itself when formed into a channel and cladded to have internal reflection.
