Visible-light Plasmonic Nanolaser Uses Dark Lattice Modes

Researchers at Aalto University (Espoo, Finland) are the first to develop a plasmonic nanolaser that operates at visible light frequencies and uses so-called dark lattice modes. The lifetimes of light captured in nanolaser dimensions are so short that the light wave has time to wiggle up and down only a few tens or hundreds of times. The results open new prospects for on-chip coherent light sources, such as lasers, that are extremely small and ultrafast.
