Characterization of Plasmonic Nanolasers in Spatial, Momentum, and Frequency Spaces

Plasmonic nanolasers are a new class of laser device where surface plasmons are amplified by the stimulated emission in a plasmonic nanocavity. In contrast to conventional lasers, the physical size and the mode volume of plasmonic nanolasers can shrink beyond the optical diffraction limit. The strongly confined optical field leads to high performance of plasmonic nanolasers including ultrafast mod...
