Polarization-insensitive integration of nanoparticle-on-a-slit cavities with dielectric waveguides for on-chip surface enhanced Raman spectroscopy
Abstract In the nanoparticle-on-a-slit (NPoS) cavity, a variation of the nanoparticle-on-a-mirror geometry, a metallic nanoparticle is placed on a functionalized narrow slit created on a metal plate so that two nanometric-scale gaps enable extreme plasmonic localization. For many applications, it is...
