Christmann, G.Butte, R.Feltin, E.Carlin, J. F.Grandjean, N.2010-10-052010-10-052010-10-05200810.1063/1.2966369https://infoscience.epfl.ch/handle/20.500.14299/55053WOS:000258335900002The authors report room temperature polariton lasing at lambda similar to 345 nm in a hybrid AlInN/AlGaN multiple quantum well microcavity (MQW-MC) containing a GaN/AlGaN MQW active region, i.e., the achievement under nonresonant optical excitation of coherent light emission of a macroscopic population of polaritons occupying the lowest energy state of the lower polariton branch. This was made possible by taking advantage of the efficient relaxation of polaritons in a MQW-MC exhibiting a large vacuum Rabi splitting Omega(VRS)=56 meV.
