Abstract

Progress in studies to increase the lateral brightness B_lat of broad area lasers is reviewed. B_lat=P_out/BPP_lat is maximized by developing designs and technology for lowest lateral beam parameter product, BPP_lat, at highest optical output power P_out. This can be achieved by limiting the number of guided lateral modes and by improving the beam quality of low-order lateral modes. Important effects to address include process and packaging induced wave-guiding, lateral carrier accumulation and the thermal lens profile. A careful selection of vertical design is also shown to be important, as are advanced techniques to filter out higher order modes.
