The plasmonic mode gap due to cutoff angular frequency enables strong optical confinement in a subwavelength volume and suppression of radiation loss. Due to strong field overlap of the surface plasmon polariton mode with environmental material, large sensitivity (1,100nm/refractive index unit) and a high figure of merit (330) are achieved in the plasmonic cavity with a small physical size of 600 × 800 × 2,500nm having a telecommunication resonant wavelength. This plasmonic cavity can introduce a broad range of applications including biochemical sensing and strong light-matter interactions.
