We report on a reliable fabrication process enabling the integration of dielectric and metallic nanostructures on the tip of optical fibers. The proposed fabrication procedure involves conventional deposition and nanopatterning techniques, typically used for planar devices, but here adapted to directly operate on optical fiber tip. We fabricate and characterize an optical fiber sensor tip based on Localized Surface Plasmon Resonances (LSPRs) for chemical and biochemical detection. A sensitivity of 125 nm/RIU for detecting changes in the bulk refractive indices in liquids, has been demonstrated. © 2014 Springer Science+Business Media.

Abstract
We report on a reliable fabrication process enabling the integration of dielectric and metallic nanostructures on the tip of optical fibers. The proposed fabrication procedure involves conventional deposition and nanopatterning techniques, typically used for planar devices, but here adapted to directly operate on optical fiber tip. We fabricate and characterize an optical fiber sensor tip based on Localized Surface Plasmon Resonances (LSPRs) for chemical and biochemical detection. A sensitivity of 125 nm/RIU for detecting changes in the bulk refractive indices in liquids, has been demonstrated. © 2014 Springer Science+Business Media.File in questo prodotto:
