“…The multilayer is made of a Ag, a SiO 2 and a Pd layer. Ag is chosen since it is well known as a good candidate for SPR sensors [19]. The Ag layer can be replaced by a Au layer -to avoid the oxidation during the fabrication -or any other metal such as Al or bi-metal [20].…”

Abstract:A new design of a fiber optic Surface Plasmon Resonance (SPR) sensor using Palladium as a sensitive layer for hydrogen detection is presented. In this approach, a transducer layer is deposited on the outside of a multimode fiber, after removing the optical cladding. The transducer layer is a multilayer stack made of a Silver, a Silica and a Palladium layer. The spectral modulation of the light transmitted by the fiber allows to detect the presence of hydrogen in the environment. The sensor is only sensitive to the Transverse Magnetic polarized light and the Traverse Electric polarized light can be used therefore as a reference signal. A more reliable response is expected for the fiber SPR hydrogen sensor based on spectral modulation instead of on intensity modulation. The multilayer thickness defines the sensor performance. The silica thickness tunes the resonant wavelength, whereas the Silver and Palladium thickness determine the sensor sensitivity. In an optimal configuration (NA = 0.22, 100 μm core radius and transducer length = 1 cm), the resonant wavelength is shifted over 17.6 nm at a concentration of 4% Hydrogen in Argon for the case of the 35 nm Silver/ 100 nm Silica/ 3 nm palladium multilayer.

“…[7] is the SPR term derived by Xu et al (Eq. [9]) and the left-hand term is the Fresnel equation for reflection off of the retro-reflector for TM mode light as a function of incident angle. This term is raised to the 2N rather than N power as in Eq.…”

“…The exposed core is then coated with an SPR supporting metal and the sensor is used in a single-pass configuration. 7,8,9 A fundamental difference between an optical fiber and the common Kretschmann configuration is that in a multimode optical fiber, the allowed incident angles are a continuum from the critical angle of the fiber as set by the numerical aperture to /2 from normal. As has been demonstrated both experimentally and theoretically, this has the effect of significantly broadening the SPR peak.…”

Fiber-optic gas phase surface plasmon resonance (SPR) detection of several contaminant gases of interest to state-of-health monitoring in high-consequence sealed systems has been demonstrated. These contaminant gases include H 2 , H 2 S, and moisture using a single-ended optical fiber mode. Data demonstrate that results can be obtained and sensitivity is adequate in a dosimetric mode that allows periodic monitoring of system atmospheres. Modeling studies were performed to direct the design of the sensor probe for optimized dimensions and to allow simultaneous monitoring of several constituents with a single sensor fiber. Testing of the system demonstrates the ability to detect 70mTorr partial pressures of H 2 using this technique and <280 μTorr partial pressures of H 2 S. In addition, a multiple sensor fiber has been demonstrated that allows a single fiber to measure H 2 , H 2 S, and H 2 O without changing the fiber or the analytical system.

The performance of a simple gold (Au)-deposited optical fiber sensor system based on surface plasmon resonance (SPR) is presented. Our sensor system comprises a light-emitting diode (LED) and a photodiode (PD) as the light source and the detector, respectively. The response curves and sensor properties of the Au-deposited optical fiber with a Au film thickness of 45 nm obtained by using three LEDs with 563, 660, and 940 nm emissions were investigated. The sensor properties depend strongly on the wavelength of the incident light and can be controlled by changing the LED emission wavelength. The response curves of the sensor obtained at the three wavelengths and calculated using SPR theoretical equations were compared with those obtained by experimentation. Our sensor system represents a new SPR-based refractometer with performance almost equal to that of an Abbe refractometer. To demonstrate its usefulness, ethanol concentrations in various spirits were measured and the results compared with those as labeled.
