Abstract
Embodiments of the invention relate to a plasmonic laser including a substrate and a coaxial plasmonic cavity formed on the substrate and adapted to facilitate a plasmonic mode. The plasmonic laser further includes an electrical pumping circuit configured to electrically pump the plasmonic laser. The coaxial plasmonic cavity includes a peripheral plasmonic ring structure, a central plasmonic core and a gain structure arranged between the peripheral plasmonic ring structure and the central plasmonic core. The gain structure includes one or more ring-shaped quantum wells as gain material. The one or more ring-shaped quantum wells have a surface that is aligned orthogonal to a surface of the substrate. The electrical pumping circuit is configured to pump the plasmonic laser via the peripheral plasmonic ring structure and the central plasmonic core.
