报告摘要: Nanolasers generate coherent light at the nanoscale. In the past decade, they have attracted intense interest, because they are more compact, faster and more power-efficient than conventional lasers. Thanks to their fundamentally new capabilities, nanolasers are now an emergent tool for a variety of practical applications. In this talk, we explain the intrinsic merits of nanolasers and assess recent progress on their application, particularly in the directions of optical interconnects, near-field spectroscopy and sensing, optical probing for biological systems and far-field beam synthesis through near-field eigenmode engineering. We highlight the scientific and engineering challenges that remain for forging nanolasers into powerful tools for nanoscience and nanotechnology.
