Abstract

We show that SERS from monolayer 4-Aminothiophenol (4-ATP) bonded to a plasmonic gap waveguide is directed into a single mode with >99% efficiency. Although sacrificing a confinement dimension, we find a 103 x SERS enhancement across a broad spectral range, enabled by the plasmonic waveguide9s larger sensing volume and non-resonant waveguide mode. Waveguide-SERS (W-SERS) is bright enough to image Raman transport across the waveguides. This exposes the roles of nanofocusing, the Purcell effect and the spontaneous Raman scattering factor, or Raman β-factor.
