TL;DR: In this article, a photonic crystal fiber (PCF) sensor composed of an indium tin oxide (ITO) coating on the outer surface based on surface plasmon resonance (SPR) is designed and investigated.

TL;DR: In this article, the current status of photonic crystal fibers (PCF) sensors based on surface plasmon resonance (SPR) is summarized, and simulation methods for PCF-SPR sensors are described.

TL;DR: In this article, an ex-centric core photonic crystal fiber sensor with gold nanowires based on surface plasmon resonance was designed and analyzed by the finite element method, and the influence of the structural parameters of the sensor on the spectral sensitivity and resonance wavelength was studied for analyte refractive indexes (na) between 1.33 and 1.4.

TL;DR: A surface plasmon resonance (SPR) chemical sensor comprising microstructured optical fiber (MOF) is designed for refractive index (RI) sensing in the visible to near-infrared (NIR) region (0.42-1.60 µm) as well as detection of gas-liquid pollutants as discussed by the authors.

TL;DR: In this paper, double-sided gold films are used to increase coupling effects between the plasmonic mode and the fundamental mode to increase the sensitivity of a hollow dual-core photonic crystal fiber.
