title = "Interaction Between a Plasmonic Nano-Resonator and a Whispering Gallery Mode Photonic Resonator Described Through Coupled Mode Theory and Experiment",
abstract = "A Whispering gallery mode (WGM) based micro-spherical resonator driven by an optical fiber and adorned with a plasmonic SiO2/Au nano-shell receptor is capable of zeptogram sensitivity for cancer marker detection from its frequency shift upon binding, making it an excellent candidate for an ultra-sensitive label-free biosensor. In this chapter we describe the experimental assembly of this hybrid resonator, obtain frequency shift and linewidth broadening data for single nanoshell binding events, and compare this data to coupled mode theory (CMT). A complex interaction g∼ describes coupling between the photonic and nano-plasmonic resonators. The shift in resonance frequency is Re [g∼ ] and the spectral line broadening is. The linewidth broadening is found to be consistent with the extinction (scattering and absorption) of the WGM evanescent wave by the nanoshell. Use of the Reactive Sensing Principle suggests a new technology for purifying nanoshells by resonance frequency, using light forces that accompany the assembly mechanism.",
