Abstract [en]

A new concept for dual parameter fiber optic sensorhas been developed and characterized, both in a two-fiber andsingle-fiber configuration. The liquid sensor measures ethanolconcentration with a stimuli responsive hydrogel whichconstitutes a low finesse Fabry-Perot cavity, and refractive indexwith a Mach-Zehnder type fiber optic interferometer. The two-fiber configuration utilize a fiber optic 1310/1550 nm wavelengthdivision multiplexer to separate the two parameters, while aversatile filtering algorithm extracts and separates the twoparameters in the single-fiber configuration. No cross talk wereobserved for the measured parameters of free spectral range andrefractive index for the two-fiber configurations, while for thesingle fiber configuration cross-talk were observed. The twoconfigurations prove to be versatile dual parametric fiber opticsensor concepts for accurate detection of specific parameters,based on stimuli responsive hydrogels.
