Titanium dioxide (TiO2) has several attractive properties such as high linear and nonlinear refractive indices and the wide bandgap for applying the nonlinear optical devices. We have been studied channel waveguides with TiO2 as the submicron size core to verify their feasibility as the nonlinear optical devices. In this study, we analyzed optical propagation in the TiO2 photonic crystal waveguide and demonstrated the enhanced optical nonlinearity due to slow light effect.
