Fiber SPR refractive index sensor with the variable core refractive index
Applied Optics, 2020In this paper, a refractive index sensor based on the control of the fiber core refractive index is proposed. By employing ultraviolet curable adhesive with the different refractive index and hollow capillary fiber, the special fiber with a variable core refractive index is fabricated.

A Refractive Index Sensor Based on PCF With Ultra-Wide Detection Range
IEEE Journal of Selected Topics in Quantum Electronics, 2021An ultra-wide detection range refractive-index sensor based on surface plasmon resonance (SPR) with photonic crystal fiber (PCF) is designed and discussed. The central air-hole of the fiber is injected with the analyte. The properties of refractive-index

Ultrasensitive optofluidic resonator refractive index sensor
Optics Letters, 2018We report an optofluidic resonator refractive index sensor based on an integrated structure constructed by a free-space coupling architecture. It uses a symmetrical metal-cladding hollow-core waveguide and a prism to generate surface plasmon polarization.

Microstructured optical fiber refractive index sensor
Optics Letters, 2010We describe a dual-core microstructured optical fiber designed for refractive index sensing of fluids. We show that by using the exponential dependence of intercore coupling on analyte refractive index, both large range and high sensitivity can be achieved in the one device.

A novel plasmonic refractive index sensor based on gold/silicon complementary grating structure
Chinese Physics B, 2021A novel complementary grating structure is proposed for plasmonic refractive index sensing due to its strong resonance at near-infrared wavelength. The reflection spectra and the electric field distributions are obtained via the finite-difference time ...

Novel optical refraction index sensor
SPIE Proceedings, 2011This works describes a novel optical refraction index sensor which is based on the analysis of double reflection lecture detection. This process initially identifies the thickness of a semitransparent solid o liquid material by the retro-reflection of a laser diode at 633nm as a function of distance along the device under test with a Z-axis scanner ...
