Design of 1060nm tapered lasers with separate contacts

Numerical simulations have been used to produce advanced designs of high brightness gain guided tapered lasers emitting at 1,060 nm. The simulations predicted high modulation efficiency in devices with separate contacts and low front facet reflectivity. The devices fabricated following these design guidelines demonstrated high internal quantum efficiency in Broad Area lasers, output power of 3 W with good beam quality in tapered lasers with common contacts, and modulation efficiencies up to 20 W/A in tapered lasers with separate contacts, in good agreement with the simulation predictions.
