Abstract :
The authors report on strategies to achieve lasing in electrically driven vertical cavity surface emitting lasers at room temperature, namely the improvement of the quality factor of a microcavity suited for electrical injection, the use of a ZnO contact together with a dielectric current confinement layer and oxidized AlInN/GaN distributed Bragg reflectors.
