The nonlinear optical rectification of an ellipsoidal quantum dot with impurity in the presence of an electric field

► Nonlinear optical properties of an ellipsoidal QD are investigated. ► Optical properties of this system are studied in the presence of an electric field. ► The OR coefficient is obviously influenced by the confinement strength and ellipticity constant. ► The presence of a donor impurity shifts the OR coefficient peak positions to higher energies.
