“…These fibers also improve sensitivity. The other designs for SPR-based fiber optic sensor includes SPR probe at one of the ends of the fiber with the reflecting end face [37,38] and a fiber tip [39,40]. The photonic bandgap fiber based SPR sensors have also been reported very recently [41,42].…”

Surface plasmon resonance technique in collaboration with optical fiber technology has brought tremendous advancements in sensing of various physical, chemical, and biochemical parameters. In this review article, we present the principle of SPR technique for sensing and various designs of the fiber optic SPR probe reported for the enhancement of the sensitivity of the sensor. In addition, we present few examples of the surface plasmon resonance-(SPR-) based fiber optic sensors. The present review may provide researchers valuable information regarding fiber optic SPR sensors and encourage them to take this area for further research and development.

“…The sensor was estimated to have an LOD of 5.2 × 10 −4 RIU. The possibility of using excitation of SPP was studied by Abrahamyan et al [ 91 ]. They used the tip of a gold-coated conical-shaped optical fibre to measure ethanol concentrations in specific solutions when the tip was dipped in the medium with a particular dielectric permittivity.…”

A range of optical fibre-based sensors for the measurement of ethanol, primarily in aqueous solution, have been developed and are reviewed here. The sensing approaches can be classified into four groups according to the measurement techniques used, namely absorption (or absorbance), external interferometric, internal fibre grating and plasmonic sensing. The sensors within these groupings can be compared in terms of their characteristic performance indicators, which include sensitivity, resolution and measurement range. Here, particular attention is paid to the potential application areas of these sensors as ethanol production is globally viewed as an important industrial activity. Potential industrial applications are highlighted in the context of the emergence of the internet of things (IoT), which is driving widespread utilization of these sensors in the commercially significant industrial and medical sectors. The review concludes with a summary of the current status and future prospects of optical fibre ethanol sensors for industrial use.

“…The energy transfer from WGM to SPP modes has been thoroughly investigated in several studies, taking into account not only the "outer" SPP modes at the outer metal surface, but also the "inner" SPP modes at the inner metal surface; in some studies, non-conical taper profiles have been scrutinized as well [40,[43][44][45]. The WGM has to present proper characteristics in order for the excited surface plasmons to exhibit axial symmetry, thereby interfering constructively at the tip apex and therefore generating nanofocusing.…”
