The effects of a double-cladding structure, made on an active layer and consisting of a quaternary buffer layer and an InP layer, on LPE-grown InGaAsP/InP lasers in the 1.5 µm range are reported. A smoother hetero-interface, lower threshold current density and smaller threshold current temperature dependence were obtained in comparison with DH lasers having only a quaternary cladding layer. As for reliability, no undersirable effects due to the insertion of an additional buffer layer have been found.
