Gas-source molecular beam epitaxy growth of GaxIn1-xAsyP1-y layers lattice-matched to GaAs is reported. X-ray diffraction, photoluminescence, and Hall measurements show that the layers are of good quality. High-performance Al-free (In)GaAs(P)/ GaxIn1-xAsyP1-y quantum well lasers, emitting at 0.8 ≤ λ ≤ 1.1 µm, and GaAs/GaxIn1-xAsyP1-y heterojunction diodes are also demonstrated. The results are comparable to those obtained for the best AlGaAs based materials and devices. In particular, we report on the first tensile-strained GaAsP/GaInAsP/GaInP quantum well laser.
