Abstract
The optical absorption of parabolic quantum dots (QDs) with different confining potentials energies in the \(\rho \) and z directions under external electric and magnetic fields are studied theoretically. We have applied the compact-density-matrix approach and iterative method to obtain the linear and nonlinear optical absorption coefficients (OAs). The energy levels and confined wave function of the system are acquired by the effective-mass approximation. The results indicate that the resonant peak values of linear and nonlinear OAs are affected by the size, the radius, incident optical intensity and the electric field. The position of the OAs peak shifts when the values of radius and magnetic field change.
