【Abstract】 Theoretical predictions of polaron effects on the third harmonic generation in a rectangular quantum wire with an additional parabolic potential were presented. The formula for the third harmonic generation along the wire was derived by the density matrix method. The numerical results were presented for a typical GaAs quantum wire.更多还原
