Diseño y caracterización de reflectores incoherentes de retrodispersión de fibra microperforada para láseres random de fibra óptica
Galarza Galarza, Marko
; Sañudo-Lasagabaster, Silvia; Pérez Herrera, Rosa Ana ; Roldán Varona, Pablo; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (SEDOPTICA, 2021)
Contribución a congreso / Biltzarrerako ekarpena 
Los láseres random de fibra óptica presentan una serie de características que los hacen idóneos para una gran variedad de aplicaciones industriales. La elevada longitud de fibra necesaria en la cavidad debido a sus bajos ... -
Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles
Lievens, Hans; Vernieuwe, Hilde; Álvarez-Mozos, Jesús ; Baets, Bernard de; Verhoest, Niko E. C. (MDPI, 2009)
Artículo / Artikulua
In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ... -
Gamma radiation measurements using an optical fiber laser
Pérez Herrera, Rosa Ana ; Stancalie, Andrei; Cabezudo Sánchez-Valverde, Pablo Miguel; Sporea, Dan; Negut, Daniel; López-Amo Sáinz, Manuel (Optical Society of America, 2018)

A fiber ring laser cavity configuration was used to analyze the effect of gamma-irradiation over the performance of different types of erbium doped fibers. Preliminary results validates this method to monitor gamma-radiation ... -
Hybrid Raman‑erbium random fiber laser with a half open cavity assisted by artificially controlled backscattering fiber refectors
Pérez Herrera, Rosa Ana ; Roldán Varona, Pablo; Sañudo-Lasagabaster Ibáñez, Silvia; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (Springer Nature, 2021)

Este trabajo presenta un láser de fibra tipo random (LFR) en cavidad semi-abierta, mediante amplificación híbrida Raman-Erbio y asistida por reflectores de fibra con retrodispersión controlada artificialmente (RFRCA). ... -
Stable L-band fiber laser sensor using a backscattering-based multimode fiber reflector
Pérez Herrera, Rosa Ana ; Roldán Varona, Pablo; Sánchez-González, Arturo; Durán Lázaro, María ; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena
A new and highly stable L-band fiber laser for sensing is demonstrated. An emission line at 1575.47 nm, was achieved using a special reflector. Good strain sensitivity, optical signal to noise ratio and output power stability ... -
Superbackscattering antenna arrays
Liberal Olleta, Íñigo ; Ederra Urzainqui, Íñigo ; Gonzalo García, Ramón ; Ziolkowski, Richard W. (IEEE, 2015)
Artículo / Artikulua
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering ... -
Wideband backscattering reduction at terahertz using compound reflection grating
Orazbayev, Bakhtiyar ; Rodríguez Ulibarri, Pablo ; Beruete Díaz, Miguel (Optical Society of America, 2017)
Artículo / Artikulua
Backscattering reduction is usually achieved by using either absorbers or diffractions gratings at the expense of a narrow bandwidth. In this paper, we propose a different strategy based on a metallic compound reflection ...
