Molecular beam epitaxy growth of 1.3 µm high-reflectivityAlGaAsSb/AlAsSb Bragg mirror

Abstract
The first high reflectivity (R = 97.7%) Al0.3Ga0.7As0.5Sb0.5/AlAs0.59Sb0.41 Bragg mirror lattice matched to InP was obtained at 1.28 µm by solid source molecular beam epitaxy. This result was achieved with only 15.5 periods in the stack. A comparison between the calculated and the measured Bragg mirror reflectivities shows a near perfect agreement.
