A multimode fiber refractive index sensor [PDF]
2016 IEEE SENSORS, 2016 We present a simple refractive index sensor based on multimode fibers realized by stripping three different lengths of cladding. We theoretically explain and experimentally validate three mechanisms occurring in the multimode fiber for sensing surrounding refractive index.

A macrobending singlemode fiber refractive index sensor for low refractive index liquids [PDF]
Photonics Letters of Poland, 2010 An all-fiber refractive index sensor with a simple configuration is proposed and investigated. The proposed fiber refractometer consists of a full-loop structure of bare high-bend loss singlemode fiber-1060XP, employing the well-known whispering gallery mode (WGM) effect induced by the evanescent wave excitation to measure the refractive index of an ...
