Ultrahigh refractive index sensing performance of plasmonic quadrupole resonances in gold nanoparticles
The refractive index sensing properties of plasmonic resonances in gold nanoparticles (nanorods and nanobipyramids) are investigated through numerical simulations. We find that the quadruple resonance in both nanoparticles shows much higher sensing figure of merit (FOM) than its dipolar counterpart, which is attributed mainly to the reduction in resonance linewidth. More importantly, our result...
متن کاملUniversal scaling of plasmonic refractive index sensors.
We establish experimental and numerical evidence that the refractive index sensitivities of various subwavelength plasmonic sensors obey a simple universal scaling relation that the sensitivities linearly increase with λm/neff (where λm is the resonant wavelengths and neff is the effective refractive index of the environment) and exhibit a slope equal to 1 instead of 2 predicted theoretically. ...
متن کاملPlasmonic Refractive Index Sensor with High Figure
A plasmonic refractive index (RI) sensor based on metal-insulator-metal (MIM) 11 waveguide coupled with concentric double rings resonator (CDRR) is proposed and investigated 12 numerically. Utilizing the novel supermodes of the CDRR, the FWHM of the resonant wavelength 13 can be modulated, and a sensitivity of 1060 nm/RIU with high figure of merit (FOM) 203.8 is realized 14 in the near-infrared...
متن کاملRefractive index sensing and surface-enhanced Raman spectroscopy using silver–gold layered bimetallic plasmonic crystals
Herein we describe the fabrication and characterization of Ag and Au bimetallic plasmonic crystals as a system that exhibits improved capabilities for quantitative, bulk refractive index (RI) sensing and surface-enhanced Raman spectroscopy (SERS) as compared to monometallic plasmonic crystals of similar form. The sensing optics, which are bimetallic plasmonic crystals consisting of sequential n...
متن کاملPlasmonic circular resonators for refractive index sensors and filters
A plasmonic refractive index sensor based on a circular resonator is proposed. With all three dimensions below 1 μm, the sensor has a compact and simple structure granting it ease-of-fabrication and ease-of-use. It is capable of sensing trace amounts of liquid or gas samples. The sensing properties are investigated using finite elements method. The results demonstrate that the plasmonic sensor ...
