Abstract
A monolithically fabricated magnetically-actuatable opto-mechanical on/off switch includes a pair of planar optical waveguides, the first waveguide of the pair being fixed in position and the second waveguide of the pair being movable between a conducting orientation wherein it is in optical alignment with the one waveguide and a non-conducting orientation wherein it is not in optical alignment with the one waveguide. A ferromagnetic component is fixedly secured to the movable second waveguide for movement therewith as a unit. A magnet may be provided for moving the ferromagnetic component, and hence for moving the movable second waveguide between the conducting and non-conducting orientations.
