The paper presents an optical fiber Bragg grating (FBG) accelerometer, using a modified cantilever beam design to get the highest possible strain in the FBG and a wide natural frequency. This accelerometer modeled a system composed by a mass mounted at the free end of a cantilever beam, which is also attached to an optic fiber whose length is varied by the movement of the mass. The objective is to...
Commercial Erbium doped silica fibers fabricated through the modified chemical vapor deposition and direct nanoparticle deposition processes where concentration is varied in a wide range are characterized by means of analyses of fluorescence decay kinetics and nonlinear absorption coefficient at 978-nm pumping. Through theoretical modeling of the results of the entire experiment,...
