Abstract
An optical bypass switch includes a variable diffraction element responsive to acoustical signals operable to couple light signals incident to first and second input ports to first and second output ports, respectively, for a first diffraction index and from the first and second input ports to the second and first output ports, respectively, for a second diffraction index. Acoustical signals are provided by an electro-acoustic transducer coupled to the variable diffraction element which establishes acoustical signals in response to acoustical signals coupled thereto.
