文摘

A theoretical study of the optical gain and the line-width enhancement factor (α-parameter) in cubic ZnO/ZnMgO quantum well laser is presented. The laser is designed to operate at ultraviolet (UV) spectrum at room temperature. This study is based on the density matrix theory including the Lorentzian broadening, with intraband relaxation taken into account. The investigation of the evolution of the optical gain and the line-width enhancement factor parameter as a function of carrier’s densities and for different values of quantum well width is proposed. It is found that the cubic ZnO/ZnMgO quantum well laser is an efficient structure emitting in UV region spectrum.
