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.KeywordsOptical FiberLocalize Surface Plasmon ResonanceFiber CoreSpin Coating TechniqueStandard Single Mode FiberThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
