Enhanced optical fiber lasers and optical fiber sensors assisted by micro-drilled optical fibers
Pérez Herrera, Rosa Ana
; Bravo Acha, Mikel ; Roldán Varona, Pablo; Leandro González, Daniel ; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena 
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are demonstrated. Strain sensitivity improved more than one order of magnitude in comparison with FBG sensors using a 50 μm-waist micro-drilled taper ... -
Micro-drilled optical fiber for enhanced laser strain sensors
Pérez Herrera, Rosa Ana ; Bravo Acha, Mikel ; Roldán Varona, Pablo; Leandro González, Daniel ; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (SPIE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
In this work, we present an experimental measurement of temperature and strain sensitivities of a micro-drilled optical fiber (MDOF). The MDOF consisted of a quasi-randomly distributed reflector along a single mode fiber ... -
Microdrilled tapers to enhance optical fiber lasers for sensing
Pérez Herrera, Rosa Ana ; Bravo Acha, Mikel ; Roldán Varona, Pablo; Leandro González, Daniel ; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (Nature Research, 2021)
Artículo / Artikulua
In this work, an experimental analysis of the performance of different types of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror is presented. These artificially-controlled ... -
Multiparameter sensor based on a multiinterferometric serial configuration for temperature and strain measurements
Pérez Herrera, Rosa Ana ; Bravo Acha, Mikel ; Leandro González, Daniel ; Novais, Susana; Pradas Martínez, Javier ; López-Amo Sáinz, Manuel (IEEE, 2021)
Artículo / Artikulua
In this work, a multi-parameter point sensor based on the combination of Fabry-Perot (FP) and the anti-resonant (AR) reflecting guidance in cascade configuration is proposed and experimentally demonstrated. This structure, ... -
Multiplexing optical fiber Fabry-Perot interferometers based on air-microcavities
Pérez Herrera, Rosa Ana ; Novais, Susana; Bravo Acha, Mikel ; Leandro González, Daniel ; Silva, Susana; Frazão, Orlando; López-Amo Sáinz, Manuel (SPIE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors ... -
WDM and TDM interrogation by sequentially pulsing direct modulated DFBs
Pérez-González, A.; Bravo Acha, Mikel ; Leandro González, Daniel ; Pérez Herrera, Rosa Ana ; López-Amo Sáinz, Manuel (Optica, 2020)
Contribución a congreso / Biltzarrerako ekarpena
A new versatile and cost-effective interrogation system by pulsing direct modulated (DM) DFB laser diodes is proposed. 1 pm wavelength resolution and 600 m sensor spacing is demonstrated by sequentially pulsing a DM DFB.
