Pickering %A Ortwin Hess %J Physics %D 2013 %I arXiv %X We present a plasmonic waveguide where light pulses are stopped at well-accessed complex-frequency zero-group-velocity points. Introducing gain at such points results in cavity-free, "thresholdless" nanolasers beating the diffraction limit via a novel, stopped-light mode-locking mechanism. %U http://arxiv.org/abs/1301.5995v1
