Abstract

The large third-order susceptibility of CdTe nanoparticles doped in polymer were measured with the Z-scan technique. The quantum confinement and the surface trapped state effects are the possible origins of the enhancement of optical nonlinearity.

Abstract

Nonlinear refraction coefficient of the third-order susceptibility of silica aerogel was estimated to be ~ -1.5 x 10-15 m2/W (~ -3.67 x 10-9 esu) by a signal-beam z-scan technique with ~1 ps Ti:Sapphire lasers. The large nonlinear refraction is originated mainly from the direct excitation to the surface trapped states, and the one-photon resonance process.
