The linear and nonlinear optical properties of a series of samples formed by the sequential implantation of Ti, O and Au are examined. Energies of implantation for each ion were chosen using TRIM calculations to insure overlap of the ion distributions. The Ti was implanted with nominal doses of 1.2 and 2 {times} 10{sup 17} ions/cm{sup 2}. The samples were implanted with oxygen to the same nominal dose as the Ti. Au was then implanted with a nominal dose of 6 {times} 10{sup 16} ions/cm{sup 2}. The samples were subsequently annealed in oxygen at 900 C for two hours. The Ti and O are incorporated into the host network, while the Au forms nanosize colloids. The presence of the Ti in the substrate causes a shift in the surface plasmon resonance frequency of the Au metal colloids as well as an increase in the nonlinear response of the composites. The results are interpreted in terms of effective medium theory
