Plasmonic 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 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 کاملGuided-Mode-Leaky-Mode-Guided-Mode Fiber Interferometer and Its High Sensitivity Refractive Index Sensing Technology
A cascaded symmetrical dual-taper Mach-Zehnder interferometer structure based on guided-mode and leaky-mode interference is proposed in this paper. Firstly, the interference spectrum characteristics of interferometer has been analyzed by the Finite Difference-Beam Propagation Method (FD-BPM). When the diameter of taper waist is 20 μm-30 μm, dual-taper length is 1 mm and taper distance is 4 cm-6...
