Optically pumped, monolithic, all-epitaxial 1.56 /spl mu/m vertical cavity surface emitting laser using Sb-based reflectors

摘要

The authors demonstrate, for the first time, 77 K CW operation of an optically pumped, monolithic, all-epitaxial vertical cavity laser, emitting at 1.56 /spl mu/m. The laser incorporates 15 and 20 period Al/sub 0.12/Ga/sub 0.88/As/sub 0.56/Sb/sub 0.44/-AlAs/sub 0.56/Sb/sub 0.44/ distributed Bragg reflectors for the top and bottom mirrors, respectively. The entire structure was grown in a single growth run by molecular beam epitaxy.
