We introduce a reliable fabrication process enabling the integration of dielectric and metallic nanostructures on the tip of optical fibers. It involves conventional deposition and nanopatterning techniques typically used for planar devices, but here adapted to directly operate on optical fiber tip. Following this approach, we demonstrate a first technological platform based on the integration, onto the optical fiber tip, of two-dimensional (2D) hybrid metallo-dielectric nanostructures supporting localized surface plasmon resonances (LSPR), that can be efficiently used for label free chemical and biological sensing and as a microphone for acoustic wave detection.
