Journal ArticleDOI
Single-shot distributed temperature and strain tracking using direct detection phase-sensitive OTDR with chirped pulses.
Juan Pastor-Graells,Hugo F. Martins,Andres Garcia-Ruiz,Sonia Martin-Lopez,Miguel Gonzalez-Herraez +4 more
TL;DR: It is demonstrated that by acting on the phase profile of the optical pulses, it is possible to introduce important conceptual and practical changes to the traditional ΦOTDR operation, thus opening a door for new possibilities which are yet to be explored.
Journal ArticleDOI
Optically controlled slow and fast light in optical fibers using stimulated Brillouin scattering
TL;DR: In this article, the authors demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fiber, achieved by means of the gain and loss mechanisms of stimulated Brillouin scattering in the fiber itself.
Journal ArticleDOI
Distributed sensing of microseisms and teleseisms with submarine dark fibers.
Ethan Williams,Maria R. Fernandez-Ruiz,Regina Magalhães,Roel Vanthillo,Zhongwen Zhan,Miguel Gonzalez-Herraez,Hugo F. Martins +6 more
TL;DR: Observations of microseism, local surface gravity waves, and a teleseismic earthquake along a 4192-sensor ocean-bottom DAS array offshore Belgium are reported, suggesting significant potential of DAS in next-generation submarine seismic networks.
Journal ArticleDOI
Coherent Noise Reduction in High Visibility Phase-Sensitive Optical Time Domain Reflectometer for Distributed Sensing of Ultrasonic Waves
Hugo F. Martins,Sonia Martin-Lopez,Pedro Corredera,Massimo L. Filograno,Orlando Frazão,Miguel Gonzalez-Herraez +5 more
TL;DR: In this paper, the authors present an experimental and theoretical description of a high-visibility phase-sensitive optical time domain reflectometry (φOTDR) and its performance when used for ultrasonic vibration measurements.
Journal ArticleDOI
Distributed Brillouin Fiber Sensor Assisted by First-Order Raman Amplification
Félix Rodríguez-Barrios,Sonia Martin-Lopez,Ana Carrasco-Sanz,Pedro Corredera,Juan Diego Ania-Castanon,Luc Thévenaz,Miguel Gonzalez-Herraez +6 more
TL;DR: In this paper, the authors have developed a new technique to significantly extend the measurement distance of a distributed Brillouin Optical Time-Domain Analysis (BOTDA) sensor by using distributed Raman Amplification in the sensing fiber.
