Refractive index change and absorption coefficient of T shaped quantum wires: comparing with experimental results

Abstract

In this work, we have studied the optical properties of a GaAs/Al $$_{x}$$ Ga $$_{1-x}$$ As T-shaped quantum wire. In this regard, we have obtained the refractive index change and absorption coefficient. We have also studied the temperature effect on absorption coefficient. The results show that the refractive index change and absorption coefficient decrease and shift towards higher energies when temperature increases. Finally, to check our results, we have compared the absorption coefficient obtained from this work with experimental data at 5 K. Our theoretical prediction has some deviations with experimental data.
