Özet
The nonlinear optical rectification, the second harmonic generation coefficient, and the third
harmonic generation coefficient in parabolic-inverse parabolic-parabolic quantum wells
(PIPPQWs) and inverse parabolic-parabolic-inverse parabolic quantum wells (IPPIPQWs) are
calculated varying the intense laser field (ILF) parameter (α0). The modifications of the dipole
moment matrix elements and the energy levels are depending on the potential shape. The results
show that the ILF intensity exerts an active influence on the profile, height, and width of the
confinement potential of both PIPPQW and IPPIPQW. The potential profile of IPPIPQW has
been affected otherwise than PIPPQW for different ILF intensities. The nonlinear optical
rectification, the second harmonic generation, and the third harmonic generation coefficients of
PIPPQW and IPPIPQW could be altered in the energy range and the size of the resonance peak
by rising the ILF intensity. By changing the α0 parameter, it is conceivable to organize red or
blue shift at the resonance peak positions of the nonlinear optical rectification, the second
harmonic generation, and the third harmonic generation coefficients. The shift of the nonlinear
optical rectification coefficient occurs when the difference between the ground and the second
energy levels changes. According to the parameters used here, while for PIPPQW the spectrum
of the resonance peak of the nonlinear optical rectification displays a blue shift with increasing
ILF, this spectrum displays a red shift for IPPIPQW. The consequences can be valued in
investigating new ways of changing the optical and electronic properties of semiconductor
quantum wells.
