Characterization of a FBG sensor interrogation system based on a mode-locked laser scheme

Madrigal-Madrigal, Javier; Fraile-Pelaez, Francisco Javier; Zheng, Di; Barrera Vilar, David; Sales Maicas, Salvador (The Optical Society, 2017-10-02)

[EN] This paper is focused on the characterization of a fiber Bragg grating (FBG) sensor interrogation system based on a fiber ring laser with a semiconductor optical amplifier as the gain medium, and an in-loop electro-optical ...
Microwave Photonic Filtering for Interrogating FBG-Based Multicore Fiber Curvature Sensor

Zheng, Di; Madrigal-Madrigal, Javier; Barrera Vilar, David; Sales Maicas, Salvador; Capmany Francoy, José (Institute of Electrical and Electronics Engineers, 2017-10-15)

[EN] We propose and experimentally demonstrate an approach to perform high-resolution and temperature-insensitive interrogation of a fiber Bragg grating (FBG)-based multicore fiber (MCF) curvature sensor using a microwave ...
Multicore fiber-Bragg-grating-based directional curvature sensor interrogated by a broadband source with a sinusoidal spectrum

Zheng, Di; Madrigal-Madrigal, Javier; Chen, Hailan; Barrera Vilar, David; Sales Maicas, Salvador (The Optical Society, 2017)

[EN] A simple, spectral-drift-insensitive interrogation scheme for a multicore fiber Bragg grating (FBG)-based directional curvature sensor is proposed. The basic principle is to transform the wavelength shift of FBGs into ...
Strongly coupled multicore fiber with FBGs for multipoint and multiparameter sensing

Liu, Zhiming; Zheng, Di; Madrigal-Madrigal, Javier; Villatoro, Joel; Antonio-Lopez, Enrique; Schuelzgen, Axel; Amezcua-Correa, Rodrigo; Zou, Xihua; Pan, Wei; Sales Maicas, Salvador (Elsevier, 2020-09)

[EN] A compact optical fiber sensor by embedding fiber Bragg gratings (FBGs) in strongly coupled multicore fiber (SCMCF) is proposed for multipoint and multiparameter sensing. To build the device, two FBGs with different ...
Temperature-insensitive curvature sensor based on Bragg gratings written in strongly coupled multicore fiber

Liu, Zhiming; Zheng, Di; Madrigal-Madrigal, Javier; Villatoro, Joel; Antonio-Lopez, J. Enrique; Schülzgen, Axel; Amezcua-Correa, Rodrigo; Zou, Xihua; Pan, Wei; Sales Maicas, Salvador (The Optical Society, 2021-08-15)

[EN] A novel temperature-insensitive optical curvature sensor has been proposed and demonstrated. The sensor is fabricated by inscribing fiber Bragg gratings with short lengths into a piece of strongly coupled multicore ...
