Material gain engineering in GeSn/Ge quantum wells integrated with an Si platform

It is shown that compressively strained Ge(1−x)Sn(x)/Ge quantum wells (QWs) grown on a Ge substrate with 0.1 ≤ x ≤ 0.2 and width of 8 nm ≤ d ≤ 14 nm are a very promising gain medium for lasers integrated with an Si platform. Such QWs are type-I QWs with a direct bandgap and positive transverse elect...
