Graded-index separate confinement double heterostructure (GRIN-SCH) InGaAs/GaAs lasers with various cavity lengths were tested in the lab. The 100m wide oxide strip lasers consists of two pairs of 10nm In0.2Ga0.8As quantum-well (QW). The barriers of the lasers are 10nm GaAs (undoped). The lasers give a lasing wavelength around 970nm at room temperature. The refractive index of the active InGaAs layer is 3.4.
