Plasmonic Nanolasers: Fundamental Properties and Applications
Nanophotonics, 2021 Plasmonic nanolasers are a new class of coherent emitters where surface plasmons are amplified by stimulated emission in a plasmonic nanocavity. In contrast to lasers, the physical size and mode volume of plasmonic nanolasers can shrink beyond the ...
