Plasmonic Lasers Get a Sharper Focus

RESEARCH NEWS Plasmonic Lasers Get a Sharper Focus Stewart Wills   In the Lehigh team’s “antenna feedback” approach, the plasmonic-laser cavity is enclosed between two metal films, with periodic slits on the top film. One SPP wave is confined inside the 10-micron-thick cavity; the other, with a larger spatial extent, is located on top of […]

Self-consistent description of graphene quantum amplifier

Self-consistent description of graphene quantum amplifier

The development of active and passive plasmonic devices is challenging due to the high level of dissipation in normal metals. One possible solution to this problem is using alternative materials. Graphene is a good candidate for plasmonics in the near-infrared region. In this paper, we develop a quantum theory of a graphene plasmon generator. Lozovic […]
