All solid source molecular beam epitaxy growth of1.35 µm wavelengthstrained-layer GaInAsP quantum well laser

Abstract
The first GaInAsP based laser diode grown by all solid source molecular beam epitaxy is reported. A strained-layer GaInAsP/InP separate confinement heterostructure multiquantum well laser emitting at 1.35 µm was prepared. A low threshold current density of 510 A/cm2 was obtained for a broad-area laser having a cavity length of 1300 µm.
