Plasmonic Nanolasers Without Cavity, Threshold and Diffraction Limit
using Stopped Light    [PDF]

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.
