摘要: Microstructured optical fibers (MOFs) represent a promising platform technology for fully integrated next generation surface enhanced Raman scattering (SERS) sensors and plasmonic devices. In this paper we demonstrate silver nanoparticle substrates SERS detection within MOF templates with exceptional temporal mechanical stability, using organometallic precursors high-pressure chemical deposition technique. These 3D offer significant benefits over conventional planar geometries, the long electromagnetic interaction lengths of guided fiber modes exciting multiple plasmon resonances along fiber. The large response detected when analyte molecules are infiltrated structures can be directly related to profile nanoparticles MOFs via electrical characterization.
