Intersubband optical absorption in InAs/In0.52 Al0.48As quantum wire in the presence of tilted electric field

In this paper, we report a theoretical study of the optical properties of InAs/In0.52Al0.48As quantum wire subjected to an inclined transverse electric field. For this purpose, we have used the effective mass approximation. The energy levels and the wave function of the ground and the first excited states have been calculated for different values of the electric field. The intersubband transition energy, the oscillator strength and the optical absorption coefficient have been also investigated. Thus, the effect of the tilt angle and the intensity of the electric field on the optical properties of the quantum wire, along the width direction, have been examined.
