    Characterization of a hybrid Fabry-Pérot Cavity based on a four-bridge double-Y-shape-core microstructured fiber
    (SPIE, 2014-06-02) Rodrigues Pinto, Ana Margarida; López Aldaba, Aitor; López-Amo Sáinz, Manuel; Frazão, Orlando; Santos, José Luís; Baptista, José Manuel; Baierl, Hardy; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa; Institute of Smart Cities - ISC
    In this work, a hybrid Fabry-Perot interferometer based on a novel four-bridge microstructured fiber is presented and characterized. The characterization of this cavity is performed in the L-band using two different instruments: an optical spectrum analyzer and an optical backscatter reflectometer. The Fabry-Perot output signal presents linear variation with temperature changes (sensitivity 9.8-11.9 pm/ºC), variation with the polarization states of light and high stability.

    All-fiber lasers through photonic crystal fibers
    (Science Wise Publishing & De Gruyter, 2013) Rodrigues Pinto, Ana Margarida; López-Amo Sáinz, Manuel; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    A review on all-fiber lasers based on photonic crystal fibers is presented. Photonic crystal fibers present improved features beyond what conventional optical fibers can offer. Due to their geometric versatility, photonic crystal fibers can present special properties and abilities which can lead to enhanced lasing structures. A brief description of photonic crystal fibers and fiber laser’s properties is presented. All-fiber laser structures developed using photonic crystal fibers are described and divided in two groups, depending on the cavity topology: ring cavity fiber lasers and linear cavity fiber lasers. All-fiber lasers applications in the photonic crystal fiber related sensing field are described.

    Experimental and numerical characterization of a hybrid Fabry-Perot cavity for temperature sensing
    (MDPI, 2015) López Aldaba, Aitor; Rodrigues Pinto, Ana Margarida; López-Amo Sáinz, Manuel; Frazão, Orlando; Santos, José Luís; Baptista, José Manuel; Baierl, Hardy; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    A hybrid Fabry-Pérot cavity sensing head based on a four-bridge microstructured fiber is characterized for temperature sensing. The characterization of this cavity is performed numerically and experimentally in the L-band. The sensing head output signal presents a linear variation with temperature changes, showing a sensitivity of 12.5 pm/°C. Moreover, this Fabry-Pérot cavity exhibits good sensitivity to polarization changes and high stability over time.

    An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber
    (MDPI, 2013) Rota Rodrigo, Sergio; Rodrigues Pinto, Ana Margarida; Bravo Acha, Mikel; López-Amo Sáinz, Manuel; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    A photonic crystal fiber-based sensing head is proposed for strain measurements. The sensor comprises a Hi-Bi PCF sensing head to measure interferometric signals in-reflection. An experimental background study of the sensing head is conducted through an optical backscatter reflectometer confirming the theoretical predictions, also included. A cost effective setup is proposed where a laser is used as illumination source, which allows accurate high precision strain measurements. Thus, a sensitivity of ~7.96 dB/me was achieved in a linear region of 1,200 μe.
