Wide‐angle electro‐optic switch

A new electric‐field‐actuated optical switch capable of wide‐angle deflection is described. The switch element makes use of the high angular selectivity of thick Bragg gratings and can be fabricated both in bulk and in thin‐film configurations. Experimental verification of the switch action in a bulk configuration is presentd. Modulation of 35% was observed in this first observation of the effect.
