Nonlinear optical properties in a quantum well with the hyperbolic confinement potential

We have performed theoretical calculation of the nonlinear optical properties in a quantum well (QW) with the hyperbolic confinement potential. Calculation results reveal that the transition energy, oscillator strength, second-order nonlinear optical rectification (OR), geometric factor and nonlinear optical absorption (OA) are strongly affected by the parameters (alpha,sigma) of the hyperbolic confinement potential. And an increment of the parameter alpha reduces all these physical quantities, while an increment of the parameter sigma enhances them, but not for geometric factor. In addition, it is found that one can control the optical properties of QW by tuning these parameters. (C) 2011 Elsevier B.V. All rights reserved.
