Acousto-optic modulation of optical reflection properties in fiber Bragg gratings and the application in fiber lasers
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2015-09-11)
This thesis aims to investigate the interaction of acoustic waves and fiber Bragg gratings (FBGs) in standard and suspended-core fibers (SCFs), to evaluate the influence of the fiber, grating and modulator design on the ...
Desenvolvimento e caracterização de encapsulamentos para redes de Bragg em fibras óticas aplicados em medição de temperatura
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2019-02-06)
In this work, several temperature sensors were produced and encapsulated using fiber optic Bragg grating (FBG). FBGs were written in the infrared band using standard telecommunication single mode optical fiber (G-652). The ...
Simple wavelength-to-phase mapping FBG's interrogation method
(Elsevier, 2014-04)
In this work, an interrogation method for FBG sensors is presented based on a wavelength-to-time transformation procedure. The proposed scheme uses an externally modulated broadband source, an optical circulator and three ...
Análise temporal do espectro óptico em redes de Bragg em fibra
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2008)
This work presents the time analysis of the Bragg wavelength shift in fiber gratings based on the elastodynamics theory and viscoelastic theory. The model is valuable for estimating the maximum tuning speed when traction ...
Desenvolvimento de um sensor de salinidade utilizando redes de Bragg corroídas em fibra óptica
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2021-11-30)
The measurement of salt concentration in brine tanks is done manually and with limited accuracy. Generally, the Baumé areometer is used, 1 ºBe in its scale can lead to an error of approximately 1% in the salt concentration, ...
Improvement of performance in FFH-OCDMA systems by using strong apodized fiber Bragg gratings
(SPIE-INT SOC OPTICAL ENGINEERING, 2004-01-01)
This paper shows simulations of an all-fiber fast optical code division multiple access communications system (OCDMA), using strong apodized fiber Bragg gratings (FBGs) arrays as passive encoding-decoding devices. Auto and ...
