Abstract

The properties and low pressure organometallic vapor phase epitaxy of Ga_xIn$1-x)P/(AlGa)_0.5In_0.5P quantum well (QW) laser diode heterostructures with Al_0.5In_0.5P cladding layers, and having wavelength 614 < (lambda) < 754 nm, are described. At longer wavelengths ((lambda) > 660 nm), threshold current densities under 200 A/cm² and efficiencies greater than 75% result form a biaxially- compressed GaInP QW active region. Although short wavelength laser performance is diminished by the poor electron confinement afforded by AlGaInP heterostructures, good 630 nm band performance is achieved with strained, single QW active regions. The wavelength range may also be expanded into the previously difficult 700-nm band, by including InGaAsP or AlGaAsP QWs.
