Resumo
An analytical formulation and modeling of an optical
fiber Bragg gratings has been developed and is reported in this
paper. Supported by the coupled-mode theory and considering
that the mode fields of the unperturbed waveguide remain
unchanged in the presence of weak perturbations, it is possible
to obtain first-order differential equations that have solutions
for some types of periodic perturbations. Finally, the model is
applied to analyze the influence of structural parameters of fiber
gratings, such as length, period and refractive index modulation
on its reflectivity and bandwidth.
