Abstract

A coherent array of silica spheres, which was implanted with erbium ions, showed nonlinear behavior at λ = 0.532 μm. This was attributed to a large nonlinear refraction effect, which was enhanced by the structure of the opaline matrix. In addition, near infrared photoluminescence measurements showed an overall enhancement as a function of the sphere's size. A large photoluminescence peak was found around λ = 900 nm and attributed to the lensing effect of the opaline matrix.
