Electro-optic switches and modulators are very important devices in optical communication systems. Fabrication of such devices requires materials with a second order optical nonlinearity; however, silica-based glass is largely limited in this area due to its spatial inversion symmetry. The invention of thermal poling technique in 1991 changed this picture, and a large research effort was stimulated by this discovery with the aim of creating a large permanent chi(2) in glassy materials. In this dissertation, the high second-order optical nonlinearity of the thermally poled lead-silicate glass waveguides was reported.

520 $a Electro-optic switches and modulators are very important devices in optical communication systems. Fabrication of such devices requires materials with a second order optical nonlinearity; however, silica-based glass is largely limited in this area due to its spatial inversion symmetry. The invention of thermal poling technique in 1991 changed this picture, and a large research effort was stimulated by this discovery with the aim of creating a large permanent chi(2) in glassy materials. In this dissertation, the high second-order optical nonlinearity of the thermally poled lead-silicate glass waveguides was reported.
520 $a A laser ablation setup was designed and built for the growth of lead-silicate glass thin films. Depositions under various laser fluence, substrate temperatures, background gas pressures, and post-deposition annealing temperatures were performed. Optimum growth parameters were determined for waveguide applications. Thin films with very low particle density, small particle size and relatively high uniformity were fabricated successfully.
520 $a The large nonlinearity localized within the PbO-glass layer was found by scanning the probe laser beam across an angle-polished sample, and a peak second-order nonlinear susceptibility chi(2) as high as 15 pm/V was achieved in the PbO-glass layer. A simple theoretical model based on charge transport in the different materials during poling was proposed and the complex chi(2) profile was explained. The large third-order nonlinearity of lead glass played a key role in the generation of the large second harmonic signal. The average electrooptic nonlinearity gammae-o for a waveguide mode was about a factor of three larger than for silica-based waveguides. Studies of UV stability of the induced nonlinearity, and the relations between SH signal and the thickness and type of films were also carried out.
520 $a Theoretical simulations of the channel waveguides of lead-silicate glass were performed to improve the structure design, as well as to predict the device characteristics. The electro-optic nonlinearity for an optical signal guided in the poled device was estimated to be 21.5 pm/V. For the integrated push-pull MZI waveguides with 10 mm interaction length, a half-wave voltage Vpi as low as +/-10 V will be achievable.
