Abstract
100 μm-stripe, broad-waveguide InGaAs-InGaAsP-GaAs DFB diode lasers (λ=976 nm) have been realised which exhibit narrow spectral widths (full width at half maximum) of 0.5 and 1.3 Å at CW powers of 0.5 and 1 W, respectively. 5/95% facet-coated devices have been realised which have an external differential quantum efficiency of 52% and a wallplug efficiency of 33% at 1 W.
