Plasmonic Whispering Gallery Microcavity (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption This plasmonic whispering gallery microcavity consists of a silica interior that is coated with a thin layer of silver. It improves on the quality of current plasmonic microcavities by better than an order of magnitude and paves the way for plasmonic nanolasers.
