Abstract

Surface enhanced Raman spectroscopy (SERS) is a widely known technique that exploits the highly localized plasmonic modes to probe the analyte in an ultra-small volume and concentration. Here, we present two different SERS substrates integrated on SiN platform i.e. localized surface plasmon resonance (LSPR) based bowtie antenna and surface plasmon polariton (SPP) based metal slot waveguide. Different performance parameters i.e. pump to Stokes conversion efficiency, broadband enhancement, structure size and ease of fabrication are discussed.
