    Largely tunable dispersion chirped polymer FBG 
    Min, Rui; Korganbayev, Sanzhar; Molardi, Carlo; Broadway, Christian; Hu, Xuehao; Caucheteur, Christophe; Bang, Ole; Antunes, Paulo; Tosi, Daniele; Marques, Carlos; Ortega Tamarit, Beatriz (The Optical Society, 2018-10-15)
    [EN] We demonstrate a largely tunable dispersion fiber Bragg grating (FBG) inscribed in a microstructured polymer optical fiber (mPOF). The bandwidth of the chirped FBG (CFBG) was achieved from 0.11 to 4.86 nm, which ...

    Multi-fiber distributed thermal profiling of minimally invasive thermal ablation with scattering-level multiplexing in MgO-doped fibers 
    Beisenova, Aidana; Issatayeva, Aizhan; Sovetov, Sultan; Korganbayev, Sanzhar; Jelbuldina, Madina; Ashikbayeva, Zhannat; Blanc, Wilfried; Schena, Emiliano; Sales Maicas, Salvador; Molardi, Carlo; Tosi, Daniele (Optical Society of America, 2019-03-01)
    [EN] We propose a setup for multiplexed distributed optical fiber sensors capable of resolving temperature distribution in thermo-therapies, with a spatial resolution of 2.5 mm over multiple fibers interrogated simultaneously. ...

    Thermal profile detection through high-sensitivity fiber optic chirped Bragg grating on microstructured PMMA fiber 
    Korganbayev, Sanzhar; Min, Rui; Jelbuldina, Madina; Hu, Xuehao; Caucheteur, Christophe; Bang, Ole; Ortega Tamarit, Beatriz; Marques, Carlos; Tosi, Daniele (Institute of Electrical and Electronics Engineers, 2018-10-15)
    [EN] In this work, a linearly chirped fiber Bragg grating (CFBG) inscribed in a microstructured polymer optical fiber (mPOF) has been demonstrated for detecting temperature pro- files during thermal treatments. A CFBG of ...
