Universal 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. ...

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...

Plasmonic 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 ...

Intrinsically core-shell plasmonic dielectric nanostructures with ultrahigh refractive index.

Topological insulators are a new class of quantum materials with metallic (edge) surface states and insulating bulk states. They demonstrate a variety of novel electronic and optical properties, which make them highly promising electronic, spintronic, and optoelectronic materials. We report on a novel conic plasmonic nanostructure that is made of bulk-insulating topological insulators and has a...
