摘要: Surface enhanced Raman spectroscopy (SERS) and stimulated (SRS) are well established techniques capable of boosting the strength scattering. The combination both (surface spectroscopy, or SE-SRS) has been reported using plasmonic nanoparticles. In parallel, waveguide developed nanophotonic nanoplasmonic waveguides. Here, we explore SE-SRS in We demonstrate that a combined photothermal thermo-optic effect gold material induces strong background signal limits detection limit for analyte. experimental results line with theoretical estimates. propose several methods to reduce counteract this background.
