Optical Properties of Tuned Double Quantum Well Under the Electric Field

Abstract

In this study, the effects of the electric field and structure-tune parameter on the linear, third order nonlinear and total absorption coefficients for transitions between the first three bound states of an electron confined within the tuned GaAs/ GaAlAs double quantum well are investigated. The obtained results show that the absorption spectra is susceptible to the structure parameter and the electric field. By changing the structure parameter and intensity of the electric field, it can be adjusted a blue or red shift in the absorption spectra according to purpose and these results can be used to tune and control the optical properties of tuned double quantum well.
