The stability of non-Abelian vortices in gauge theory
Yoshihiko Abe, Tetsutaro Higaki, Kazuya Murakami +2
We study the linear energetic stability of non-Abelian vortices in an gauge-Higgs theory with residual gauge group . In our previous work, we identified two families o…
Scaling of nonlinear dynamics driven by stimulated Raman scattering in gas-filled hollow-core fibers
Pau Arcos, Arturo Mena, María Sánchez-Hernández +4
Optical systems are scalable under low-intensity illumination since their governing equations are linearly dependent of the optical signal strength. Nonetheless, in high-intensity…
Stimulated Raman Scattering and Molecular Modulation in Anti-resonant Hollow-core Fibres
Pau Arcos, Arturo Mena, María Sánchez-Hernández +5
Raman scattering is the inelastic process where photons bounce off molecules, losing energy and becoming red-shifted. This weak effect is unique to each molecular species, making i…
Compact omnidirectional multicore fiber-based vector bending sensor
Josu Amorebieta, Angel Ortega-Gomez, Gaizka Durana +6
We propose and demonstrate a compact and simple vector bending sensor capable of distinguishing any direction and amplitude with high accuracy. The sensor consists of a short segme…
Sensitivity-optimized strongly coupled multicore fiber-based thermometer
Josu Amorebieta, Ángel Ortega-Gómez, Rubén Fernández +6
In this paper, we report on a multicore fiber-based (MCF) temperature sensor that operates in a wide thermal range and that is robustly packaged to withstand harsh environments. To…
Composed multicore fiber structure for direction-sensitive curvature monitoring
Joel Villatoro, Josu Amorebieta, Ángel Ortega-Gómez +4
The present work deals with a curvature sensor that consists of two segments of asymmetric multicore fiber (MCF) fusion spliced with standard single mode fiber (SMF). The MCF compr…
Highly sensitive multicore fiber accelerometer for low frequency vibration sensing
Josu Amorebieta, Ángel Ortega-Gómez, Gaizka Durana +6
We report on a compact, highly sensitive all-fiber accelerometer suitable for low frequency and low amplitude vibration sensing. The sensing elements in the device are two short se…
Twin-core fiber sensor integrated in laser cavity
Josu Amorebieta, Joao Pereira, Gaizka Durana +5
In this work, we report on a twin-core fiber sensor system that provides improved spectral efficiency, allows for multiplexing and gives low level of crosstalk. Pieces of the refer…
Generation of THz radiation through molecular modulation in hydrogen-filled hybrid anti-resonant fibers
Sebastien Loranger, Foroogh Jafari, Joseba Zubia +1
We study the generation of narrowband terahertz (THz) pulses by stimulated Raman scattering and molecular modulation in hydrogen-filled hybrid hollow-core fibers. Using a judicious…
