The nonlinear optical properties of different samples of dielectric nanocolloids and their application to generate optical spatial solitons in two transverse dimensions are investigated. Each sample is constituted by a suspension of polystyrene nanospheres in water, and we analyze four cases with two different particle sizes (62[Formula: see text]nm and 77[Formula: see text]nm in diameter) and concentrations (0.5% and 1.0% solids). The z-scan technique is used to evaluate and compare the nonlinear refractive index of the nanocolloids. A detailed experimental study on the formation of soliton-like beams as a function of different parameters is also presented. Importantly, the generated solitons propagate along distances exceeding by one order of magnitude the propagation distances observed previously in the same kind of media.

Optical Rectification

Simultaneous effects of magnetic field, pressure and temperature on the exciton binding energies are found in a 9.0 1.0 6.0 4.0 GaAs P / GaAs P quantum dot. Numerical calculations are carried out taking into consideration of spatial confinement effect. The cylindrical system is taken in the present problem with the strain effects. The electronic properties and the optical properties are found with the combined effects of magnetic field strength, hydrostatic pressure and temperature values. The exciton binding energies and the nonlinear optical properties are carried out taking into consideration of geometrical confinement and the external perturbations.Compact density approach is employed to obtain the nonlinear optical properties. The optical rectification coefficient is obtained with the photon energy in the presence of pressure, temperature and external magnetic field strength. Pressure and temperature dependence on nonlinear optical susceptibilities of generation of second and third order harmonics as a function of incident photon energy are brought out in the influence of magnetic field strength. The result shows that the electronic and nonlinear optical properties are significantly modified by the applications of external perturbations in a 9.0 1.0 6.0 4.0 GaAs P / GaAs P quantum dot.
