Graded-index separate-confinement InGaAs/GaAs strained-layer quantum well laser grown by metalorganic chemical vapor deposition

Abstract
A graded-index separate-confinement strained-layer quantum well laser with pseudomorphic Ga0.63In0.37As quantum well was grown by metalorganic chemical vapor deposition. The lasing wavelength is 0.99 μm at 300 K and the average threshold current density of broad area 146×363 μm devices is 195 A/cm2.
