Nonlinear optical properties of modified Möbius squared potential well: influence of electric and magnetic fields

Abstract

ABSTRACTThis work presents a numerical study on the electronic and optical properties of modified Möbius squared potential well in the presence of static electric and magnetic fields. The potential well is formed within GaAs/AlGaAs hetero structures. Schrödinger’s equation is solved within the framework of effective mass and envelope wave function approximations to get the wave functions and their corresponding energies of states. The optical absorption coefficients and relative refractive index changes are calculated via the expressions derived from the compact density matrix approach. The numerical results present strong blue shifts on the optical responses of modified Möbius squared potential well when the external electromagnetic fields are strengthening.KEYWORDS: Möbius quantum welloptical absorptionrefractive index changeselectric and magnetic fields Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementNo data associated in the manuscript.
