Digital alloy AlAsSb/AlGaAsSb distributed Braggreflectors lattice matched to InP for 1.3 – 1.55µm wavelength range

Abstract
The authors report a distributed Bragg reflector (DBR) consisting of 15.5 periods of AlAsSb and AlGaAsSb digital alloy with a peak reflectivity >95% at 1.46 µm. The DBR is grown by molecular beam epitaxy on an InP substrate.
