Growth/fabrication of organic-inorganic quasi phase-matching structures for frequency conversion devices

A method of making a quasi-phase-matching (QPM) structure comprising the steps of:

• (a) applying a pattern to a substrate to define a plurality of growth regions and a plurality of voids;
• (b) growing a crystalline inorganic material on only the growth regions in the pattern including one or more of the plurality of voids between adjacent growth regions, the crystalline inorganic material having a first polarity;
• (c) applying an electric field within a growth chamber containing the patterned substrate with the crystalline inorganic material, wherein the electric field reaches throughout the growth chamber;
• and
• (d) growing a crystalline organic material having a second polarity in the plurality of voids formed in the inorganic material under the influence of the electric field to influence the magnitude and the direction of the second polarity of the crystalline organic material, wherein the second polarity of the crystalline organic material is influenced so as to be different from the first polarity of the crystalline inorganic material in at least one of magnitude and direction.
