In this work a model was developed that allows to understand the behavior of a chirped fiber Bragg grating for the detection and characterization of cracks in materials. In addition to the amplitude response, we show that ...

The need for low-chirp and compact transmitters for high-bit-rate optical links has led to the development of integrated laser electroabsorption modulators (ILM). We have investigated feedback effects inducing frequency ...

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 ...

The information rate in multimode fiber optic networks decreases with great performance due to the differential modal delay since it limits the bandwidth of the cabling, the dispersion limits the speed and the dispersion ...

This work presents the production of fiber Bragg gratings with different profiles for application in sensing and in telecommunications. The gratings for sensing application were recorded using direct illumination of a phase ...
