    Fully-switchable multi-wavelength fiber laser based interrogator system for remote and versatile fiber optic sensors multiplexing structures
    (SPIE, 2014-06-02) Bravo Acha, Mikel; Miguel Soto, Verónica de; Ortigosa Cayetano, Amaia; López-Amo Sáinz, Manuel; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    A novel interrogation system for multiple fiber optic sensor technologies and based on a fully-switchable multiwavelength fiber laser (MWFL) is proposed and experimentally demonstrated. The MWFL can generate any wavelength combination with a minimum emission line distance up to 50 GHz fitting the ITU grid specifications. On the other hand, as proof of concept sensor network, two different networks were multiplexed by using a remote powered by light fiber optic switch. They are based on two different sensor technologies. One of them based on PCF intensity sensors and multiplexed by using an 8 port WDM and the other one based on wavelength temperature/strain FBG sensors.
