In this paper we report the fabrication of microstructured optical fibers (MOFs) metallic metamaterials using a bottom-up processing technique for surface enhanced Raman scattering (SERS) applications. The inner walls of the silica-based holey optical fiber have been modified by depositing granular films of Ag nanoparticles from its organometallic precursor at high pressure condition. The resulting fibers demonstrate strong SERS effect when analyte molecules are infiltrated within the MOF due to large electromagnetic field enhancement and long interaction length. The chemically modified MOFs with 3D patterning represent an exciting platform technology for next generation SERS sensors and plasmonic in-fiber integrated devices.
