Abstract

We describe the picosecond nonlinear optical response of a metal-dielectric composite made by implanting Cu ions in fused silica. The implanted Cu ions aggregate during implantation to form nanometer-diameter clusters in a dense, thin (~150 nm) layer just beneath the surface of the substrate. The third-order susceptibility X((3)) has an electronic component with a magnitude of the order of 10(-8) esu and is enhanced for laser wavelengths near the surface plasmon resonance of the copper colloids.

摘要

我们描述了通过在熔融石英中注入铜离子制成的金属-电介质复合材料的皮秒级非线性光学响应。注入的铜离子在注入过程中聚集，在衬底表面下方致密的薄（约150纳米）层中形成纳米直径的团簇。三阶极化率χ(3)具有量级为10^(-8) 静电单位的电子分量，并且对于接近铜胶体表面等离子体共振的激光波长会增强。
