Paper Abstract

A two-step proton-exchange process is employed to produce waveguides and gratings in lithium niobate. In both steps mixtures of lithium benzoate and benzoic acid are used. The fabricated components are characterized at 0.633mm and 0.442/mm. In particular, we have observed that the light intensity diffracted out into the air by the grating is about 0.5% of that in the waveguide.
