Paper Abstract

The properties and low pressure organometallic vapor phase epitaxy of GaxIn1-xP/(AlGa)0.5In0.5P quantum well (QW) laser diode heterostructures with Al0.5In0.5P cladding layers, and having a wavelength of 614 < (lambda) < 690 nm, are described. At longer wavelengths ((lambda) > 660 nm), threshold current densities under 200 A/cm2 and efficiencies greater than 75% result from 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, and extension into the 610 nm band, is achieved with strained, single QW active regions.
