Abstract

Abstract A composite having third order non-linear optical activity comprising, an organic polymer and an inorganic material. The organic polymer has third order nonlinear optical activity and the inorganic material is a sol-gel glass. The organic polymer or a precursor of the organic polymer is mutually soluble with a precursor of the sol-gel glass. The invention also includes photonic media having the above composite and a method of making the composite.
