SEMICONDUCTOR-LASERS USING DIFFUSED QUANTUM-WELL STRUCTURES

We assess the relative merits and prospects of using diffused quantum- well (QW) structures in semiconductor lasers. First, different techniq ues to achieve interdiffusion are analyzed and compared. Second, recen t development of semiconductor lasers using interdiffusion technique i s also discussed. Third, the optical properties of diffused QW's are s tudied. In addition, novel design of diffused QW's structures to maint ain stable single-mode operation in semiconductor lasers is proposed. Finally, brief discussion and conclusion are given.
