High-Sensitivity Temperature Sensing Enabled by Selective Alcohol Infusion in Hollow-Core NANF
With a novel high-efficiency selective infusion method for hollow-core NANF, a cladding ring alcohol infusion-induced modal interference is generated, with an extinction ratio of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$22 d B$</tex>, enhancing the sensor's temperature sensitivity to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$0.82 ~\text{nm} /{ }^{\circ} \mathrm{C}$</tex>.
