Abstract

An electro-optic lithium niobate waveguide switch using a symmetric 1 X 2 directional coupler structure and a two-section, unequal-length, (Delta) (beta) phase-reversal electrode is described. The device exhibits a step-like response to switching voltage. This response eliminates the need for precise voltage control to achieve low crosstalk. Switching characteristics of the device and experimental results are presented.
