Comparison Results

This paper presents a comparative analysis of some of the important characteristics of the carriers of quantum well and quantum dot based laser. Among the characteristics of the carriers, confined carrier concentrations in the gain medium as well as the carrier concentrations at the threshold have been studied extensively by using InxGa1-xN based quantum well and InxGa1-xN based quantum dot in the active layer of the laser structure. The numerical results obtained are compared to investigate the superiority of the quantum dot over quantum well. It is ascertained from the comparison results that InxGa1-xN based quantum dot provides higher density of confined carrier and lower level of carrier concentration required for lasing action. This paper reports the enhancement of confined carrier density and minimization of carrier concentration at threshold of laser using InxGa1-xN based quantum dot as the active layer material. Hence, it is revealed that better performances of lasers have been obtained using InxGa1-xN based quantum dot than that of quantum well in the active medium of the device structure.
