作者报道了在包含GaN/AlGaN MQW有源区的混合AlInN/AlGaN多量子阱微腔（MQW-MC）中在类似于345 nm的λ处的室温极化激元激光，即，在非共振光激发下实现相干光发射的宏观极化激元群体占据较低极化激元分支的最低能态。这是通过利用MQW-MC中的极化激元的有效弛豫而实现的，该MQW-MC表现出大的真空拉比分裂Ω（VRS）=56 meV。(c)2008年美国物理研究所。
The 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. (c) 2008 American Institute of Physics.
