Figure Lengend Snippet: ( a ) Schematic demonstration of the physical distances between fiber Bragg gratings (FBGs) in the cyclic transparent amorphous fluoropolymers (CYTOP) fiber. ( b ) Reflected optical spectrum of the five-sensors FBG array inscribed in 120 µm core diameter, multimode, gradient index CYTOP fiber when illuminated with broadband light source and measured using a commercial FBG spectrometer.

Article Snippet: The FBG sensors employed on the experiments were POFBGs inscribed in a gradient index multimode CYTOP fiber (Chromis Fiberoptics Inc., Warren, NJ, USA) with core diameter of 120 μm, a 20 μm cladding layer, and an additional polyester and polycarbonate over-cladding structure to protect the fiber, resulting in a total diameter of 490 μm [ ].
