The effect of terahertz laser field on the optical absorption coefficients and refractive index changes of hyperbolic confinement quantum wells

Abstract

In this paper, the potential profile with applying terahertz laser field is deduced by the Kramers-Henneberger transformation. In the frame of effective quality, the Schrödinger equation is solved to obtain the energy levels and the wave functions. Then, the variations of optical absorption coefficients (OACs) and the optical refraction index changes (ORICs) are deduced by the compact matrix approach and the iterative method. The results illustrate that the OACs and the ORICs are regulated by the terahertz laser field. The influence of the intensity of incident light on the OACs and the ORICs also are discussed.
