In this study, the effects of hydrostatic pressure, temperature, and high-frequency intense laser
field on the nonlinear optical properties of an asymmetric GaAs/AlGaAs double quantum well was theoretically investigated. For this, firstly, the energy eigenvalues and eigenfunctions of the system have been
obtained using the effective-mass and parabolic band approximation. Later, the nonlinear optical properties of the structure are calculated using the compact-density matrix approach. The obtained numerical
results show that when the magnitude of the intense laser field applied to the structure is increased, the
amplitudes of both the total optical absorption coefficients (TOACs) and the relative refractive index
changes (RRICs) peaks increase and shift towards higher energies. In addition, it was also observed that
the increase in temperature had a similar effect on the TOACs and RRICs with the intense laser field,
whereas the increase in hydrostatic pressure has an opposite effect.
