Abstract: Metal-dielectric multilayer films show high transmission at some specific wavelengths of light due to multiple Bragg reflections. By designing the multilayer structure, the high transmission position can be tuned to be on resonance with the laser wavelength at which the light can penetrate into the highly nonlinear metallic layers, leading to an enhanced nonlinear optical response. By employing a femtosecond optical Kerr technique, we experimentally investigated Ag-TiO2 multilayer stacks, and an enhanced nonlinear optical response was observed. © 2007 Optical Society of America.
