Redes de Bragg para medições em altas temperaturas
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2012-02-28)
This work presents results regarding pré-treatment optical fibers and / or post-treatment of Bragg gratings in order to stabilize and ensure the operational of such gratings for long periods at temperatures form 300 °C to ...
Leitura de redes de Bragg por modulação ótica
(Centro Federal de Educação Tecnológica do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2005)
This work presents a process to detect Bragg grating spectra based on the tunable
Fabry Perot filter technique. The apparatus is assembled with a piezoelectric actuator that
mechanically modulates a reference Bragg ...
Optimization of Fiber Bragg Grating for sidelobe reduction of reflectivity
(Institute of Electrical and Electronic Engineers (IEEE), 2022)
Design and tolerance analysis of a router with an amplified resonator and Bragg gratings
(04/20/2000)
A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB ...
Reduction of Bragg grating-induced coupling to cladding modes
