ABSTRACTTitanium oxide glasses exhibit a significant nonlinear optical response which is attributed to the large polarizability of the Ti ion. Ion implantation is a unique method for incorporating polarizable ions in glass hosts and allows for tailoring the nonlinear optical properties of the material for potential device applications in all optical switching and planar waveguide technology. However, at the molecular level, the linear and nonlinear properties of ion implanted glasses are governed by interactions between the glass host and the implanted ion, radiation damage, and ion-glass chemistry. In order to probe the host-guest interactions, we have measured the infrared and optical spectra for Ti implanted in silica, borosilicate, and aluminosilicate glasses. The infrared and optical spectra indicate that the host-guest interactions and defect concentration differ significantly for the three glasses investigated.
