Nonlinear optical properties of a three-dimensional anisotropic quantum dot

► Nonlinear optical properties of an anisotropic quantum dot are investigated. ► The optical properties of this system are studied in the presence of a magnetic field. ► The optical absorption coefficients and refractive index changes are obviously influenced by the characteristic frequency. ► The dependence of the optical absorption coefficients and refractive index changes on the dot radius is investigated.
