Nonlinear optical refraction and absorption have been measured on Si nanocrystals grown by plasma-enhanced-chemical-vapour-deposition. Strong nonlinearities were found at 830 urn and at 1552 nm. Different behaviours, depending on the pump-pulse duration, have been observed.

Abstract
Nonlinear optical refraction and absorption have been measured on Si nanocrystals grown by plasma-enhanced-chemical-vapour-deposition. Strong nonlinearities were found at 830 urn and at 1552 nm. Different behaviours, depending on the pump-pulse duration, have been observed.
