Picosecond nonlinear optical transmission measurement in SiO2/TiO2 one-dimensional photonic crystals

We fabricated SiO2/TiO2 one-dimensional photonic crystals by a sol-gel method. A picosecond pump-probe nonlinear optical measurement was performed in the one-dimensional photonic crystal, with the pump wavelength fixed at 355nm and the probe wavelength fixed at 532nm falling on the bandgap edges. The third order nonlinear optical response in an anatase TiO2 film composing the one-dimensional photonic crystal is found to be responsible for the nonlinear optical transmission changes at both bandgap edges.
