Strained-layer InGaAsP diode lasers with tapered gain region for operation at /spl lambda/=1.3 /spl mu/m

A report is given of the first high-power InP-based tapered lasers. Continuous output powers of 0.5 W with nearly 80% of the power in the central lobe have been obtained. This is the highest reported brightness of a 1.3 /spl mu/m source.<<ETX>>
