Impact of impurity on the non-linear and linear optical properties of InxGa1-XAs quantum dot

In the current investigation, we emphasise the optical properties of the InxGa1-xAs quantum dot. In this esteem, we first estimate the energy levels and wavefunctions in the existence of impurity. Then, we focus on the impact of impurity on the absorption coefficients, refractive index changes, and third harmonic generation. It is found that the absorption coefficients, refractive index changes, and third harmonic generation peaks start to shift from their position with the decrement in the magnitude as the concentration of impurity enhances. As a consequence, it is cognizance that the concentration of impurity has a crucial role in the nanostructure optical properties.
