Accurate Strain Sensing Based On Super-Mode Interference In Strongly Coupled Multi-Core Optical Fibres
; Arrizabalaga Uriarte, Oskar
; Durana Apaolaza, Gaizka ; ; ; ; (Nature Publishing Group, 2017-06-30)
We report on the use of a multi-core fibre (MCF) comprising strongly-coupled cores for accurate strain sensing. Our MCF is designed to mode match a standard single mode optical fibre. This allows us to fabricate simple MCF ... -
Compact Omnidirectional Multicore Fiber-Based Vector Bending Sensor
Amorebieta Herrero, Josu; Ortega Gómez, Ángel ; Durana Apaolaza, Gaizka ; Fernández Bello, Rubén ; ; ; ; ; (Nature, 2021-03-16)
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 segment of asymmetric multicore fiber (MCF) ... -
Composed multicore fiber structure for direction-sensitive curvature monitoring
; Amorebieta Herrero, Josu; Ortega Gómez, Ángel ; Antonio López, José Enrique; ; Schülzgen, Axel; Amezcua Correa, Rodrigo (2020-07-01)
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 comprises three strongly coupled cores; one of ... -
High-performance vector bending and orientation distinguishing curvature sensor based on asymmetric coupled multi-core fibre
Arrizabalaga Uriarte, Oskar; Sun, Qi; Beresna, Martynas; Lee, Timothy; ; Velasco Pascual, Javier; Sáez de Ocáriz, Idurre; Schülzgen, Axel; Antonio López, José Enrique; Amezcua Correa, Rodrigo; ; Brambilla, Gilberto (Nature, 2020-08-20)
Fibre optic technology is rapidly evolving, driven mainly by telecommunication and sensing applications. Excellent reliability of the manufacturing processes and low cost have drawn ever increasing attention to fibre-based ... -
Highly Sensitive Multicore Fiber Accelerometer for Low Frequency Vibration Sensing
Amorebieta Herrero, Josu; Ortega Gómez, Ángel ; Durana Apaolaza, Gaizka ; Fernández Bello, Rubén ; Antonio López, José Enrique; Schulzgen, Axel; ; Amezcua Correa, Rodrigo; (Nature, 2020-09-30)
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 segments of strongly coupled asymmetric ... -
Multi-parameter optical gauge based on mode coupling effect in asymmetric index multi-core fibres
Arrizabalaga Uriarte, Oskar; ; ; ; ; ; ; ; ; (Elsevier, 2022-07)
An optical gauge based on coupled multi-core fiber is proposed and experimentally demonstrated. By using direct laser writing to selectively break the fiber index profile symmetry, asymmetric mode coupling between cores ... -
Packaged multi-core fiber interferometer for high temperature sensing
Amorebieta Herrero, Josu; Durana Apaolaza, Gaizka ; Ortega Gómez, Ángel ; Fernández Bello, Rubén ; ; ; ; ; ; ; (IEEE, 2019-03-07)
[EN]A small size and compactly packaged optical sensor for high-temperature measurements is reported. The sensor consists of a short piece of multi-core fiber (MCF) spliced to the distal end of a single-mode fiber. The ... -
Sensitivity-optimized strongly coupled multicore fiber-based thermometer
Amorebieta Herrero, Josu; Ortega Gómez, Ángel ; Fernández Bello, Rubén ; Antonio López, José Enrique; Schulzgen, Axel; ; Amezcua Correa, Rodrigo; Durana Apaolaza, Gaizka ; (Elsevier, 2022-01)
[EN] 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 develop the sensor, the fundamentals ... -
Simultaneous Sensing of Refractive Index and Temperature With Supermode Interference
Flores Bravo, José Ángel; Fernández Bello, Rubén; Antonio López, José Enrique; ; Schülzgen, Axel; Amezcua Correa, Rodrigo; (IEEE, 2021-11-15)
[EN]In general, a sensor is used to monitor a single parameter only, and in many cases, a reference sensor is necessary to compensate the effect of temperature. Here, we demonstrate that a single supermode interferometer ...
