Modeling Optical Low-threshold Exciton Nonlinearity in Dielectric Nanocomposites

We report on calculations of exciton nonlinearity in dielectric nanocomposites. The effect of various parameters on the spectrum of nonlinear increment to the refractive index, such as size and form factor of the nanoparticles shown. Numerical simulations of the optical response of dielectric nanoparticles Al2O3 presented.
