作为纳米级相干光源,纳米线激光器具有很多应用前景。但是由于缺乏选模机制,通常多模运行。该论文通过折叠CdSe纳米线形成高反射率环形镜及多腔耦合,实现第一个低阈值单纳米线单模激光器,使纳米线向实用化迈进一步。研究结果被《Nature》、《Nature Nanotechnology》、《Photonics Spectra》等专题报道和高度评价。
As nanoscale coherent sources, nanowire lasers are promising for many applications but traditionally they operate at multi-modes due to the lacking of mode selection capability. In 2011, by folding a 200-nm-diameter CdSe nanowire into high-reflectivity loop mirrors to create coupled cavities, The paper reported the first single-nanowire single-mode laser with low threshold, which paved the way to practical applications of nanowire lasers. This work was highlighted in Nature, Nature Nanotechnology, Photonic Spectra.
