“…So they neither generate sparks nor rely on heat exchange and have no risk of gas ignition. With the development of optoelectronic technology and micromachining technology, more and more new work such as sensors based on fiber grating [6], [7], evanescent field [8], [9], metallic photonic crystal structures [10] and surface plasmon Manuscript resonance [11]- [13] are springing up. However, some of them have an all-fiber sensing system but a low sensitivity, while some others own a high sensitivity but introducing bulk-optic components which may introduce instability to optical system.…”

A new method based on introducing a photonic crystal fiber (PCF) in-line interferometer for hydrogen sensing is demonstrated. One end-face of the PCF and part of the outer-face of the fiber are plated with a thin palladium film by magnetron sputtering, while the other end is connected to the optical path. Therefore, a set of reflection-type all-fiber hydrogen sensor system is accomplished. Hydrogen concentration from 0% to 5% was detected in the experiment and the related interferometric resonant wavelength-shift was recorded. The maximum wavelength shift is over 1.2 nm. The whole system has an all-fiber optical path without any bulk-optic components, and this design obtains a high level of integration, a high stability, and low production costs.Index Terms-Photonic crystal fiber in-line interferometer, reflective, wavelength-shift, hydrogen sensor.

“…Several configurations have been proposed to overcome this limitation. Multilayer coatings have been used on top of unclad fibre sections to provide a medium with the correct refractive index for SPP excitation252627. Sensing mechanisms are based on the refractive index changes occuring in this multilayer structure when gases are adsorbed into it.…”

Ultrasensitive plasmonic sensing in air using optical fibre spectral combs

Surface plasmon polaritons (SPP) can be excited on metal-coated optical fibres, enabling the accurate monitoring of refractive index changes. Configurations reported so far mainly operate in liquids but not in air because of a mismatch between permittivities of guided light modes and the surrounding medium. Here we demonstrate a plasmonic optical fibre platform that overcomes this limitation. The underpinning of our work is a grating architecture—a gold-coated highly tilted Bragg grating—that excites a spectral comb of narrowband-cladding modes with effective indices near 1.0 and below. Using conventional spectral interrogation, we measure shifts of the SPP-matched resonances in response to static atmospheric pressure changes. A dynamic experiment conducted using a laser lined-up with an SPP-matched resonance demonstrates the ability to detect an acoustic wave with a resolution of 10−8 refractive index unit (RIU). We believe that this configuration opens research directions for highly sensitive plasmonic sensing in gas.

“…Moreover, palladium was coated on the core of the multi-mode fiber in place of noble metal, in a study, for the sensing of hydrogen gas. 25 The sensor was based on the change in the complex permittivity of palladium in the presence of hydrogen gas. The sensor was able to measure as low as 0.8% concentration of hydrogen in pure nitrogen.…”
