Abstract

Using tailored refractive-index and injection-current profiles, broad-area laser simulations demonstrate suppression of free-carrier-induced self-focusing. 7.7W of spatially stable power enables high-efficiency (>70%) coupling into SMF-28, resulting in 5.5W of fiber-coupled power for EDFA pumping.
