ABSTRACT
We have fabricated the largest integrated optical switch array to date—a square array of 16 interconnected Ti:LiNbO[sub 3] directional coupler electro-optical switches. The devices operate at ∼11 V and have 4.6-15-dB fiber-device-fiber insertion loss and extinction ratios from -12 to > -35 dB.

    LixNa2-xTi6O13 has received attention as 3??-metal oxide based anode material for possible battery application. Generally, titanium oxides represent excellent Li hosts due to their zero-strain behavior, cycling stability and high operating voltage. New developments choose Na as charge carrier,...
