论文摘要
我们通过实验证明了脊极化激光器与在电子孔种群反转下运行的常规边缘发射脊激光器之间的差异。水平激光腔为具有垂直bragg反射器的20-60 $ $ $ m $ m长的蚀刻山脊结构。我们研究光泵送下的激光阈值，并定量评估变化的光泵的长度的效果。激光效果是针对仅占空腔长度15％的激子储层长度的，这在传统的脊机激光器中是不可能的，没有反演的无极性增益大约是等效的gan激光器的大约10倍。空腔自由光谱范围的建模证明了模式的极化性质。
We experimentally demonstrate the difference between a ridge polariton laser, and a conventional edge-emitting ridge laser operating under electron-hole population inversion. The horizontal laser cavities are 20 -- 60 $μ$m long GaN etched ridge structures with vertical Bragg reflectors. We investigate the laser threshold under optical pumping and assess quantitatively the effect of a varying optically-pumped length. The laser effect is achieved for an exciton reservoir length of just 15% of the cavity length, which would not be possible in a conventional ridge laser, with an inversion-less polaritonic gain about 10 times larger than in equivalent GaN lasers. The modelling of the cavity free spectral range demonstrates the polaritonic nature of the modes.
