Abstract

A non-linear optical thin film layer system (10) is provided for integrated optics applications where a non-linear optical thin film layer (18) is integrated with a gallium-arsenide substrate (12). A first encapsulating layer (20) is deposited on lower surface (26), peripheral sides (30), and an upper surface peripheral region (28) of said gallium-arsenide substrate (12). A second encapsulating and buffer layer (14) is epitaxially grown on an upper surface of said gallium-arsenide substrate (12) and on the encapsulated upper surface peripheral region (28) of said gallium-arsenide substrate (12). A perovskite layer (16) is epitaxially grown on an upper surface of the layer (14). A non-linear optical thin film layer (18) is epitaxially grown on an upper surface of the perovskite layer (16) and is lattice matched to this layer.
