Electrooptic Bragg diffraction switches in low cross-talk integrated-optics switching matrix.
A switching matrix using electrooptic Bragg diffraction switches in a planar waveguide is described. Low cross talk is obtained because the wave propagation in a planar waveguide eliminates all waveguide junctions. Furthermore, the connections between input and output ports are formed by using the ON position of the Bragg diffraction switches only. In their OFF position, the electrooptic Bragg diffraction switches do not adversely affect the laser beams which propagate through them.
