Refractive index sensing with an air-slot photonic crystal nanocavity.

Abstract

We investigate an air-slot photonic crystal cavity for high-precision refractive index sensing. The high quality factor approximately 2.6x10(4) of the cavity, along with a strong overlap between the resonant mode and the hollow core region, allows us to achieve an experimental sensitivity of 510nm per refractive index unit (RUI) and a detection limit below… (More)
