Bragg grating inscription at 600 nm wavelength region in CYTOP POF with 248 nm KrF pulses

Min, Rui, Ortega, Beatriz, Leal-Junio, Arnaldo and Marques, Carlos (2018). Bragg grating inscription at 600 nm wavelength region in CYTOP POF with 248 nm KrF pulses. IEEE Sensors Letters ,


We demonstrate Bragg grating inscription in commercial CYTOP POF at a wavelength of 600 nm using a 248 nm krypton fluoride (KrF) excimer laser system with a repetition rate of 40 Hz and average pulse energy of 0.60-0.02 mJ during 60 min. Experimental characterization of the Bragg grating is performed under different conditions, where the temperature and strain sensitivities were accurately measured to define potential sensing and optical communication applications. Furthermore, different humidity conditions were experimentally tested and it was proved CYTOP POF as a good candidate for sensing applications under humidity change environment.
