Abstract

We have tried to model the effect of degeneracy on the tunability of wavelength in quantum dots lasers (QDLs). Quantum dots undergo 3D confinement. We obtain the energy values from the Energy of a particle in a box model. The transitions taking place between the energy levels led to emission of radiation having a wide range of wavelengths. The quantum dot size was found to have tunable effect on the wavelength of the emitted radiation.

Keywords: Quantum dots lasers, 3D confinement and tunable wavelength.
