Abstract
A high-quality AlPSb/GaPSb Bragg reflector lattice matched to InP was grown by gas-source molecular beam epitaxy, and highly reflective DBR mirrors were obtained by improving both the layer flatness and the compositional uniformity. A reflectivity of over 99% was obtained at 1.6 μm from a 20 pair AlPSb/GaPSb quarter-wave mirror, demonstrating the advantage of using this material system to fabricate long-wavelength surface-emitting lasers
