Lasing operation of InGaN/GaN/AlGaN vertical cavity surface emitting lasers
(VCSELs) was successfully realized up to room temperature under optical pu
mping. VCSELs were grown by metalorganic vapor phase epitaxy and consisted
of 2 lambda vertical cavity with twelvefold stacked ultrathin InGaN quantum
dot-like insertions in a GaN matrix and strain-compensated Al0.15Ga0.88N/G
aN distributed Bragg reflectors.
