Abstract :
We have obtained 2.5 W peak-pulsed power in a 2.6° wide beam (6.4×diffraction-limit), with 1.2 W in the central lobe, from 40-element, 250 μm aperture, 1.55 μm antiguided laser arrays. The InP-based devices have a compressively-strained InGaAsP double-quantum-well active region and are fabricated by creating a near-resonant antiguided array via a two-step self-aligned MOCVD growth. The width of the central lobe remains constant from 4 to 15×threshold
