Refractive-index sensing with ultra-thin plasmonic nanotubes

, 2012
We study the refractive-index sensing properties of plasmonic nanotubes with a dielectric core and ultra-thin metal shell. The few-nm thin metal shell is described by both the usual Drude model and the nonlocal hydrodynamic model to investigate the ...

Resonator-based nanoscale plasmonic sensor made of metal–graphene–insulator interfaces

Results in Physics
We present a nanoscale refractive index plasmonic sensor based on Fano resonance. We simulate and numerically analyze a novel double T-shaped resonator structure made of conductor–insulator waveguides.

Nanoscale Temperature Sensor with Dual Circular and Square Structures Based on MIM Waveguides

Photonics
This paper proposes a refractive index sensor with high sensitivity, which operates based on the Fano resonance phenomenon. The sensor is constructed using a metal–insulator–metal (MIM) waveguide integrated with a double square ring (DSR) configuration ...

Enhancing refractive index sensing through a cascaded Mach–Zehnder interferometer with double-tapered segment in bent fiber

AIP Advances
A novel refractive index sensor has been developed based on the Mach–Zehnder interferometer principle. This sensor was fabricated using a cascaded structure with double-tapered segments in one single mode fiber.
