UV light detection with side polished CYTOP fiber

CYTOP fiber, used mainly in strain detection and refractive index characterization of liquids, can be polished for the UV light radiation. The study investigates transmission spectra fiber exposed to different intensities light, demonstrating a linear relationship. A simplified system using single wavelength, 395 nm, shows real-time performance sensor range from 1 15 mW. results reveal potential as with sensitivity 0.65%/mW limit 0.3 mW, offering implications monitoring radiation exposure related health risks. In addition, effect was also observed at longer wavelengths lower intensity variation, which suggests could transmitting telecommunications bands.
