Abstract

The laser type semiconductor optical component comprises: a semiconductor material substrate, a bottom cladding layer containing n-type carriers, an active layer forming one of more quantum wells, and a top cladding layer containing p-type carriers. To increase the emission power of the laser without increasing the vertical divergence of the beam, the bottom cladding layer has a higher refractive index than the top cladding layer. The lasers for pumping optical fiber amplifiers.
