Abstract : We report the creation of a novel composite nonlinear optical material by implanting Cu ions in fused silica. The implanted Cu ions aggregate at room temperature to form nm-size polycrystalline clusters in a high-density thin (approx. - 150 nm) layer just beneath the surface of the substrate. Measurements of the Kerr-type third-order nonlinear susceptibility Chi(3) of this material shows that it has a response time no longer than 6ps and a magnitude of order 10(exp -8) esu. The nonlinearity is enhanced for laser wavelengths near the surface plasmon resonance of the copper colloids. (MM)
