dc.description.abstract | In this study, we have examined the nonlinear optical rectification (NOR), the second harmonic generation
(SHG), and the third harmonic generation (THG) coefficients of the AlxGa1-xAs/GaAs superlattice with a periodically increased barrier width under magnetic field (B) and electric field (F). All calculations are completed using the finite element method under the effective mass approximation. The electric field’s polarity (±) changes the probability density of wavefunctions. For B = 0, F = - 5 kV/cm (particularly for the difference between energy levels (Efi)) is a critical value. Whereas the Efi value decreases between - 40 <F < - 5 kV/cm, then it increases in the range of - 5<F < 40 kV/cm. This change causes a red or blue shift in the optical spectrum. We also see that F = 40 kV/cm causes a change in the transition energies of the structure more than F = - 40 kV/cm. The confinement of electrons under applied magnetic fields occurs in the center of the superlattice. The NOR, SHG, and THG coefficients can be adjusted over a wide energy range and size of the resonance peak with changes in the F and B values. It is believed that with the combined effect of the electric and magnetic fields, the electrooptical properties of the superlattices can be tuned for the desirable property of semiconductor optical device applications. | tr |
