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 / ArtikuluaAn 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 / ArtikuluaIn 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, ... -
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 / ArtikuluaA 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 ... -
Low noise dual-wavelength erbium fiber laser in single-longitudinal-mode operation
Rota Rodrigo, Sergio ; Pérez Herrera, Rosa Ana ; Fernández Vallejo, Montserrat ; López-Amo Sáinz, Manuel (Springer, 2012) Artículo / ArtikuluaA new stable dual-wavelength fiber-ring laser based on erbium-doped fiber amplification is reported. The laser is based on ring resonators and employs fiber Bragg gratings to select the operation wavelengths. The ... -
Narrow-linewidth multi-wavelength random distributed feedback laser
Leandro González, Daniel ; Rota Rodrigo, Sergio ; Ardanaz, Diego; López-Amo Sáinz, Manuel (IEEE / OSA, 2015) Artículo / ArtikuluaIn 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 / ArtikuluaWe 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 ... -
