<p>A reverse (Alpha) (Beta) optical switch employs spatial tapering of the distance (D (2)) between a pair of optical waveguides (10, 11) for efficient straight-through transmission. Appropriate choice of effective coupling strengths for the TE and TM polarization modes achieves efficient crossover transmission. A split electrode configuration (13, 14, 15) permits the application of uniform electric fields (V1=V2) or reversed electric fields (V1=-V2) across the waveguides. </p> |
