Effective linear and third-order nonlinear optical properties of metal/dielectric composites are studied. We take into account the interaction between metal particles and dielectric matrix by introducing an interfacial factor I via a simple model. Explicit expressions for the effective linear dielectric function Єe(0) and cubic nonlinear susceptibility χe(3), which are dependent on I and the mean radius a of metal particles (or the annealing temperature TA), are derived with Taylor expansion methods. We find that the interfacial factor I plays an important role in determining both the linear and nonlinear optical properties. Our theoretical results are in agreement with the observed dependence of the linear absorption coefficient α and the nonlinear susceptibility χe(3) on the mean radius a (or TA). © 2000 American Institute of Physics.
