Abstract
An optical fiber refractive index sensor based on localized surface plasmon (LSP) resonances within resonant subwavelength apertures in a gold film is demonstrated. The excitation of LSPs within the apertures in the film on the optical fiber endfaces provided the basis of a compact refractive index sensor for liquids. A sensitivity of 755 ± 12 nm per refractive index unit was demonstrated for this sensor. © 2013 AIP Publishing LLC.
