Cosendey, G.Feltin, E.Castiglia, A.Carlin, J.-F.Altoukhov, A.Levrat, J.Christmann, G.Butte, R.Grandjean, N.2010-10-112010-10-112010-10-11200910.1364/CLEO.2009.CMEE6https://infoscience.epfl.ch/handle/20.500.14299/55377WOS:000274751300197The 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 AllnN/GaN distributed Bragg reflectors.
