Is it possible to combine two or more optical materials in such a manner that the effective nonlinear optical susceptibility of the composite material exceeds those of its constituents? Recent theoretical and experimental results indicate it is possible, and suggest that the construction of composite materials may constitute a generally useful method for obtaining materials with desirable nonlinear optical properties.
