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…

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…
