Abstract

A hybrid plasmonic microcavity consisting of a silicon microdisk which is separated from a silver toroidal strip by a low-permittivity dielectric is proposed to achieve high quality factor as well as small mode volume. Mode properties such as quality factor, effective mode volume and energy ratio have been investigated by employing a finite element method and analyzed considering the different structure geometry. Simulation results reveal that this kind of hybrid microcavity maintains low propagation loss with high quality factor ~ 7000, high field limits with small mode volume 0.315 μm³, high energy ratio and can realize a refractive index sensor with high sensitivity.
