Abstract

Single narrow stripe ridge-waveguide modified triple-quantum-well AlGaAs lasers were fabricated with high reflection and anti-reflection facet coatings. The maximum cw output power exceeded 100 mW and kink-free power was up to 80 mW. The device had a characteristic temperature of 320 degree(s)K and a threshold current density of 480 A/cm2. A lateral spreading current as large as 20 mA was found. The aspect ratio of the far-field beam pattern was four while the astigmatism was measured to be less than 5 micrometers . The dependence of the parallel beam divergent angle on the ridge width was also investigated.
