Paper Abstract

We demonstrate novel plasmon resonator geometries consisting of ultra-smooth metal surfaces that support surface plasmon polariton modes exhibiting record-high quality factors in the visible frequency range. The resonators are utilized to achieve record narrow-linewidth, low-threshold surface-plasmon-polariton lasing at optical frequencies, as well as exhibit high figure-of-merit sensing. The lasing threshold of the plasmon-laser was further minimized by leveraging grating-coupled plasmons to pump the lasing-plasmons with strong spatial overlap and minimum perturbation. The results predict potential applications in small-volume optical sensing or energy-efficient coherent on-chip optical sources.
