Réduction en bande de base des distorsions non-linéaires dans les systèmes OFDM optiques cohérents basés sur les SOAs : analyse stochastiques et expérimentales

Abstract : With the demand for higher data rates, optical communication systems are seeking to meet certains specifications in terms of data rate, transmission range, and flexibility. With the recent technological advances, the question of digital signal processing possibilities arises for access and metropolitain networks. This thesis focuses, on the hand, on transmissions using semiconductor optical amplifiers, and on the other hand, on multi-carrier modulations. These amplifiers make it possible to increase the usable optical bandwidth while limiting the cost of the architecture. This type of modulation, here OFDM modulation, gives the operator a certain flexibility while increasing the spectral efficiency . The combinaison of these amplifiers and the OFDM modulation generates non-linaerities that will negatively affect the transmission system. Trough numerical, experimental, and stochastic analyses, this thesis helps to establish the feasibility and advantages of digital predistorsion and post-distorsion in terms of improving overall transmission quality , increasing transmission range, and robustness to system variability.
