摘要：

In this paper, a high-Q/V-eff gap-mode plasmonic Fabry-Perot nanocavity, which is composed of a silver nanowire on a flat silver substrate spaced by patterned dielectric distributed Bragg gratings, is investigated both analytically and numerically. The design parameters and properties of the nanocavity are exploited with the use of generalized Fabry-Perot model. The V-eff similar to 0.0026 (lambda/n)(3) and Q/V-eff similar to 1.4 x 10(5)/mu m(3) of the nanocavity can be achieved. Such a gap-mode plasmonic Fabry-Perot nanocavity design provides a promising realization for wide novel band filters and spaser. (C) 2013 Optical Society of America
