• The dielectric confinement effect on the nonlinear optical properties of composite materials is studied using the effective medium approximation. It is shown that both off-resonance and resonance dielectric enhancement of nonlinear susceptibilities occur in semiconductor particles doped in linear dielectric materials. Resonance enhancement of third-order susceptibility is associated with excitations of the surface exciton polaritons of the electric multipole modes in the semiconductor particles. The resonance frequency shows a blue shift with the volume fraction of the semiconductor. The effect is numerically evaluated for direct band-gap semiconductors such as CuCl, CdS and GaAs nanocrystals doped in glass.
