Comparative study of ring and random cavities for fiber lasers
Fernández Vallejo, Montserrat
; Rota Rodrigo, Sergio ; López-Amo Sáinz, Manuel (Optical Society of America, 2014)
Artículo / Artikulua 
An experimental comparison of three fiber laser structures with the same Raman gain medium is presented in order to establish the main pros and cons of each basic scheme. The first fiber laser is based on a hybrid ring–random ... -
Compound lasing fiber optic ring resonators for sensor sensitivity enhancement
Rota Rodrigo, Sergio; González Herráez, Miguel; López-Amo Sáinz, Manuel (IEEE / OSA, 2015)
Artículo / Artikulua
In this work, a new method for increasing simultaneously the sensitivity and interrogation stability of fiberoptic intensity sensors is presented. The configuration is based on a double-coupler ring resonator. On one side, ... -
Development of advanced structures for optical fiber lasers and sensors
Rota Rodrigo, Sergio (2015)
Tesis doctoral / Doktoretza tesia
Desde la irrupción de la fibra óptica en las telecomunicaciones, han surgido multitud de desarrollos basados en sus propiedades. Así, en las últimas décadas, la rápida evolución de los sistemas basados en fibra óptica, así ... -
An in-reflection strain sensing head based on a Hi-Bi photonic crystal fiber
Rota Rodrigo, Sergio; Rodrigues Pinto, Ana Margarida ; Bravo Acha, Mikel ; López-Amo Sáinz, Manuel (MDPI, 2013)
Artículo / Artikulua
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 ... -
Narrow-linewidth multi-wavelength random distributed feedback laser
Leandro González, Daniel; Rota Rodrigo, Sergio ; Ardanaz, Diego; López-Amo Sáinz, Manuel (IEEE / OSA, 2015)
Artículo / Artikulua
In this work, narrow-band emission lines are generated by means of two random distributed feedback fiber laser schemes. Spectral line-widths as narrow as 3.2 pm have been measured, which significantly improves previous ... -
Remote (250 km) fiber Bragg grating multiplexing system
Fernández Vallejo, Montserrat; Rota Rodrigo, Sergio ; López-Amo Sáinz, Manuel (MDPI, 2011)
Artículo / Artikulua
We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ... -
Simultaneous measurement of humidity and vibration based on a nanowire sensor system using Fast Fourier Transform technique
Rota Rodrigo, Sergio; López Aldaba, Aitor ; Pérez Herrera, Rosa Ana ; López Bautista, María del Carmen; Esteban, Óscar; López-Amo Sáinz, Manuel (IEEEOptical Society of America, 2016)
Artículo / Artikulua
This paper presents a new sensor system for vibration and relative humidity measurements based on its interaction with the evanescent field of a microwire. The interrogation of the sensing head is carried out by monitoring ... -
Single-longitudinal mode laser structure based on a very narrow filtering technique
Rodríguez Cobo, L.; Quintela, M. A.; Rota Rodrigo, Sergio; López-Amo Sáinz, Manuel ; López Higuera, José Miguel (Optical Society of America, 2013)
Artículo / Artikulua
A narrow filtering technique based on the spectral overlapping of two uniform FBGs and applied to obtain a Single Longitudinal Mode (SLM) laser is proposed and demonstrated in this work. The two FBGs are spectrally detuned ... -
