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 ...
