Abstract :
Summary form only given. 0.78 μm, Al-free active-region, compressively-strained (Δa/a=0.85%) InGaAsP quantum well diode lasers have been grown by MOCVD. Broad-stripe (100 μm-wide) devices exhibit low threshold current densities, 290 A/cm2 (L=1 mm), and cw front-facet output powers of 2.2 W
