The work presents the effects of hydrostatic pressure and temperature on the electronic spectra as well as on the optical responses of parabolically shaped asymmetric triple quantum wells formed between the GaAs/Al0.3Ga0.7As heterostructures. The electronic structure of the configuration is obtained by iteratively solving the Schrödinger equation within effective mass and envelope wave function approximations. Optical properties are calculated within the compact density matrix approach framework. The results in this study show that increasing hydrostatic pressure field leads to small redshifts on the total optical absorption coefficient, relative refractive index change, nonlinear optical correction, and second and third harmonic generations, while temperature augmentation causes significant redshifts in these optical properties.
