Abstract
Nanoplasmonic stopped-light lasing is a recently established principle [1] that not only opens the door to ultrafast cavity-free nanolasing, ultra-thin lasing sufaces exploiting van Hove singularities [2] and cavity-free quantum-electrodynamics but also provides an entry point to quantum gain in quantum plasmonics. We show that engineered singularities in the density of optical states realised in a metal-dielectric-metal nano-waveguide structure lead to a stopped-light feedback mechanism that is the basis for the dynamics of the observed cavity-free photonic and surface-plasmon polariton nanolasing. The condensed surface plasmon polaritons are characterised by ultrafast spatio-temporally oscillating amplified surface-plasmon polaritons on ultrafast timescales <5 femtoseconds and with spatial periods on the nanoscale <100 nm.
