Design and analysis of an ultra-high sensitivity quasi-D-shaped SPR photonic crystal fiber sensor for chemical and industrial liquid detection

Design of a high-precision fiber-optic sensor based on Tamm plasmon polaritons.

The application of optical fiber sensing structures based on plasmon regulation is hindered in high-precision detection scenarios by issues such as broad spectral full width at half maximum (FWHM), high energy loss, and intricate structural configurations. In this paper, an optical fiber sensing structure based on a Ta...

Dual-core wide detection range D-shaped photonic crystal fiber dual parameters sensor based on surface plasmon resonance

A dual-core D-shaped photonic crystal fiber sensor based on surface plasmon resonance is proposed for simultaneous detection of refractive index and temperature.

High-Performance Photonic Crystal Biosensors using Sub-wavelength Nanopillars

Photonic-crystal (PC) slabs composed of subwavelength silicon pillars erected on a thin silicon backing layer, with heights of only one or half lattice constant, are simulated for optical biosensing by numerical solution of Maxwell's equations. Localized optical cavity modes that form waveguides in the direction of bio...
