Abstract

In the present work plasmonic properties of metal nanocrystals, monocrystalline gold or silver nanocubes, nanorods, or nanocages deposited on planar substrates or on tilted fiber Bragg grating (TFBG) sensors have been fine tuned to enhance the performance of such novel sensing platforms. Superior refractive index sensitivities of nanocrystal/substrate or nanocrystal/TFBG have been observed and correlated with their plasmonic properties. Surface enhancement of Raman signal using nanocrystal coated TFBG was detected. The study proposes a novel fiber based sensing platform utilizing localized surface plasmon resonances.
