ABSTRACT:
The inventive process produces a Li(NbTa)O.sub.3 single-domain, single-crystalline film on a lithium tantalate single-crystal. The film is grown on the lithium tantalate, single-crystal by hydrothermal synthesis wherein the alkaline solution is heated to a temperature which is lower than the Curie point temperature of lithium tantalate. The mother material is a mixture of tantalum and lithium salts.
The resulting film may guide several modes of light, and possibly modulate them.
