We have numerically investigated the unique effects of metallic nanoparticle on the ring resonator, especially multiple Au nanoparticles on the micro ring resonator with the 4-port configuration on chip. For the Au nanoparticle, because it has smaller real refractive index than air and large absorption refractive index, we found that there is a blue shift for the ring resonance wavelength, inst...

Plasmonic nanostructures have attracted significant attention because of their unique optical properties arising from localized surface plasmon resonances (LSPR). Due to the high optical sensitivity of LSPR to size, shape, electron density, and local environments, it is possible to probe the physical and chemical processes on nanoparticles by monitoring their spectral change of LSPR. However, t...
