Abstract

High-performance diode laser oscillators and amplifiers require uniform epitaxial structures with low transparency currents and high differential gain. In the paper, the authors present device results that have followed an effort to improve the design and growth of organometallic vapor phase epitaxy (OMVPE) InGaAsP/lnP strained-layer quantum-well (SLQW) material. Broad-area laser characterization shows significant improvement in threshold current density, differential efficiency and modal-gain. Results for ridge-waveguide narrow-stripe lasers, ridge amplifiers, and tapered lasers that give record 1.3 μm power levels with near-diffraction limited beam widths are presented
