Electrical and Optical Properties of Alkoxide-Derived Lithium Niobate Thin-Layers,

Abstract

Sol-gel processing methods were investigated for the preparation of lithium niobate optical layers. Two alkoxide systems, ethanol and 2-methoxyethanol, were studied. The methods resulted in either randomly oriented polycrystalline layers on silicon or grain-oriented layers on sapphire and platinum substrates. Data are reported for the electrical and optical properties of the layers. In addition to stoichiometric lithium niobate layers, Ti:LiNbO3 was prepared by the addition of titanium alkoxides to the solutions. Optical data are presented for the Ti:LiNbO3 layers as a function of titanium content.
