RESUMO

This work describes a study of chirped fibre Bragg gratings, based on their analysis, characterization and application on dispersion compensation, for optical communication systems operating in a linear regime. It concentrates on the group delay oscillatory behaviour, observed in dispersion compensating gratings, known as Group Delay Ripple. The main scope of this work is to investigate possible solutions to that problem, rather than apodisation techniques, using numerical simulations and experimental implementations. A good agreement between both results was observed. Numerical system simulations are presented and discussed. The penalties due to the group delay oscillation is evaluated and new methods for controlling this ripple are suggested. Those techniques can be applied to long haul sytems (distances greater than 100 km and bit rates equal or greater than 10 Gb/s) operating with standard singlemodefibre
