Abstract

In this work, the effects of the Rashba and Dresselhaus spin–orbit interactions, eccentricity and external electric and magnetic fields on the linear optical absorption in an elliptical quantum ring are studied. The electronic structure is determined using the finite element method, and the linear optical absorption coefficient is calculated by the density matrix approach. Results indicate that the spin–orbit interaction and magnetic field lead to the splitting and oscillatory behavior of the energy levels, respectively. The resonant peak of the linear optical absorption shifts to the higher energies with increasing eccentricity. The magnitude and position of the resonant peaks have non-monotonic behaviors with the external fields.
