Abstract: Microstructured optical fibers, particularly those with a suspended-core geometry, have frequently been argued as efficient evanescent-field fluorescence-based sensors. However, to date there has not been a systematic comparison between such fibers and the more common geometry of a multi-mode fiber tip sensor. In this paper we make a direct comparison between these two fiber sensor geometries both theoretically and experimentally.Our results confirm that suspended-core fibers provide a significant advantage in terms of total collected fluorescence signal compared to multi-mode fibers using an equivalent experimental configuration.

Light-Sheet Skew-Ray Enhanced Pump-Absorption for Sensing

“…P UMP absorption and fluorescence [1]- [8] are well established sensing mechanisms for the detection and quantification of biological or chemical measurands for the applications of healthcare, manufacturing and security. Multimode fibers have been widely adopted for delivering light and probing local environments in evanescent-wave-based bio/chemical sensors, due to their high simplicity, high robustness and commercial availability at a low cost.…”

A Review of Optical Fibre Ethanol Sensors: Current State and Future Prospects

“…Clearly, a broad variety of optical fibre ethanol sensors, based on unique structural configurations and sensitive coatings, have been reported and their efficacy has been verified experimentally in the literature. Fluorescence-based optical fibre sensors have also been reported in limited cases, including [ 34 , 99 , 100 ]. Recent developments in whispering gallery mode type sensors have also been reported for ethanol measurement in aqueous solutions for which resonant modes are supported and the light signal circulates in a dielectric ring or microbubble.…”

Suspended-Core Microstructured Polymer Optical Fibers and Potential Applications in Sensing

“…A 532 nm laser beam was coupled into the SC-MOF and the fluorescence was delivered to the monochromator after the scattered and reflected pump light were removed with a 533 nm long pass filter. A comparison between the sensitivity of SC-MOF and conventional multi-mode fiber tip sensors has been presented in 2016 [91] showing that the SC-MOF fluorescence sensor has a significantly higher efficiency than the MMF tip sensor.…”
