Abstract
Non-linear optical materials, i.e., those optical materials whose indices refraction depend on input radiation intensity, are few and of low non-linearities; this invention uses various metallic patterns on a transparent substrate, with non-linear elements between parts of the patterns, to function as an artificial dielectric. These elements may take the form of metal-oxide-metal tunnel diodes, Schottky diodes, p-n junction diodes, superlattice structures, and non-linear capacitors.
