A reverse .DELTA..beta. optical switch employs spatial tapering of the distance between a pair of optical waveguides for efficient straight-through transmission. Appropriate choice of effective coupling strengths for the TE and SM polarization modes achieves efficient crossover transmission. A split electrode configuration permits the application of uniform electric fields or reversed electric fields across the waveguides.
