Abstract:   (4311 Views)
In the present work, first an analytic relation for position-dependent effective mass in a quantum rod is obtained. Then, the effect of position-dependent effective mass on the intersubband optical absorption coeffcient and the refractive index change in the quantum rod is examined. Our numerical calculations are performed using both a constant effective mass and the position-dependent effective mass. We calculate the linear, nonlinear and total intersubband absorption coeffcient and refractive index change as a function of the incident optical intensity and structure parameters such as rod length and rod radius. The results obtained from the present work show that spatially varying electron effective mass plays an important role in the intersubband optical absorption coeffcient and refractive index change in a quantum rod.
