Abstract:
Silicon-based laser diodes, optical amplifiers, electrooptical modulators, and photodetectors in which the active region consists of a pseudomorphic GeSn multiple quantum well stack. Each quantum well is tensile-strained Ge. sub. 1-x Sn. sub. x layer sandwiched between compressively strained barriers of Ge. sub. 1-y Sn. sub. y with x. about. 1, x
