Title: Active Metamaterials: From ‘Trapped Rainbows’ to Stopped-Light Lasing
Abstract: Metamaterials have in the last decade emerged as a new paradigm in physics, optics, engineering and nanoscience, paving the way for a multitude of unprecedented capabilities such as invisibility cloaking, perfect imaging and trapped rainbow stopping of light. In this lecture I will give an overview of recent key developments in the field of metamaterials, highlighting theoretical, computational and modeling concepts of active metamaterials for sub-wavelength imaging, invisibility cloaking and trapped-rainbow stopping of light [1,2]. Describing the complex spatio-temporal interaction between plasmons, light and quantum gain media on the nanoscale the lecture will then chart the way towards control of nanoscale quantum emitters , ultra-thin metasurfaces  and stopped-light nanolasing .
