Abstract

A time-dependent theoretical approach is developed to investigate the effects of intense terahertz (THz) laser radiation on optoelectronic properties of a two-dimensional electron gas (2DEG) in which the spin-orbit interaction is induced by the Rashba effect. It is found that for InGaAs-based spintronic systems, the electron density of states, the Fermi energy and the spin polarization are sensitive to THz laser fields. The results demonstrate that intense THz radiation can be used to enhance spin polarization and to achieve optical perturbation of the spintronic properties of a 2DEG and the Rashba spin splitting can be identified optically.
