Abstract

We have experimentally investigated the dispersion of the third order optical susceptibility χ(3) of silver nanoparticles embedded in silica glass in the vicinity of the surface plasmon resonance. The dispersion of the real and imaginary parts of the effective third order optical susceptibility χeff(3) was evaluated from the effective refractive index using a spectroscopic ellipsometry and the transient transmission and reflection changes using a femtosecond pump probe spectroscopy. The Imχeff(3) exhibits a minimum value of 1.3×1017m2/V2 at 3.03 eV. The results demonstrate that the local field factor greatly contributes to the dispersion of χeff(3) for Ag nanoparticles.
