    Bragg Grating Inscription With Low Pulse Energy in Doped Microstructured Polymer Optical Fibers 
    Min, Rui; Ortega Tamarit, Beatriz; Nielsen, K.; Bang, Ole; Marques, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2018-05)
    [EN] We demonstrate that fiber Bragg gratings (FBGs) can be written in a doped polymer optical fiber (POF) in a low ultraviolet (UV) pulse energy regime (60 ¿J/pulse) using a 248-nm krypton fluoride excimer laser system. ...

    Fabrication of tunable chirped mPOF Bragg gratings using a uniform phase mask 
    Min, Rui; Ortega Tamarit, Beatriz; Marques, Carlos (The Optical Society, 2018-02-19)
    [EN] We demonstrate chirped Bragg gratings fabrication in doped microstructured tapered polymer fibers by using a uniform phase mask. The use of high photosensitive benzyl dimethyl ketal (BDK) doped core fiber allows to ...

    Fast inscription of long period gratings in microstructured polymer optical fibers 
    Min, Rui; Marques, Carlos; Nielsen, K.; Bang, Ole; Ortega Tamarit, Beatriz (Institute of Electrical and Electronics Engineers, 2018-03-01)
    [EN] We demonstrate 20 dB long period grating (LPG) fast inscription in microstructured polymer optical fibers (mPOFs) using a point-by-point technique obtaining an LPG total length of 25 mm. Two 248 nm UV laser pulses of ...
