Nous avons proposé et démontré une nouvelle technique de stabilisation de longueur d'onde pour les systèmes de multiplexage par répartition en longueur d'onde dense (DWDM) utilisant l'annulation AM induite par tramage qui améliore à la fois la stabilité de longueur d'onde et les performances de transmission de données. Notre technique de stabilisation de longueur d'onde consiste en une fonction de discrimination de fréquence optique et une fonction d'annulation des composantes AM induites par le tramage de fréquence de la source lumineuse. La discrimination de fréquence dans cette technique est basée sur un effet de conversion FM-AM, obtenu par interaction du tramage de fréquence de la lumière avec la caractéristique passe-bande d'un multiplexeur à réseau de guides d'ondes en réseau (AWG). La fonction d'annulation AM a été ajoutée pour supprimer les erreurs de discrimination de fréquence optique se produisant en raison des composants AM induits par le tramage de fréquence dans cette architecture de stabilisation de longueur d'onde. Dans ce schéma, un modulateur d'électro-absorption (EA) est utilisé non seulement pour moduler le trafic de données à grande vitesse, mais également pour supprimer les composantes AM induites par le tramage de fréquence sur le signal lumineux. Étant donné que le modulateur EA est généralement utilisé pour moduler le trafic de données à haut débit, aucun dispositif optique dédié n'est requis pour supprimer les composants AM. La stabilité de longueur d'onde d'une source lumineuse peut donc être améliorée grâce à une architecture simple. Dans la démonstration, une réduction des fluctuations dans la plage de 50 MHz par rapport aux modifications de l'indice de modulation et une stabilité à long terme dans la plage de 320 MHz après plus de 60 heures ont été obtenues dans une transmission NRZ à 10 Gbit/s. Nous avons également confirmé que la technique d'annulation AM proposée réduit efficacement les pénalités de transmission dues au tramage de fréquence dans les performances de transmission de données NRZ à 10 Gbit/s.

Abstract: We proposed and demonstrated a novel wavelength stabilization technique for dense wavelength division multiplexing (DWDM) systems using dithering-induced AM cancellation which improves both wavelength stability and data transmission performance. Our wavelength stabilization technique consists of an optical frequency discriminating function and a function for canceling AM components induced by frequency dithering of the light source. The frequency discrimination in this technique is based on an FM-AM conversion effect, obtained by interaction from frequency dithering of the light with the bandpass characteristic of an arrayed-waveguide grating (AWG) multiplexer. The AM cancellation function was added to suppress optical frequency discriminating errors occurring due to AM components induced by frequency dithering in this wavelength stabilization architecture. In this scheme, an electro-absorption (EA) modulator is employed not only for modulating high-speed data traffic but also for suppressing AM components induced by frequency dithering on the light signal. Since the EA modulator is usually used for modulating high-speed data traffic, dedicated optical devices are not required for suppressing the AM components. The wavelength stability of a light source can therefore be enhanced with simple architecture. In the demonstration, a reduction of fluctuations within 50 MHz versus changes in the modulation index, and long-term stability within 320 MHz after more than 60 hours was achieved in 10 Gbit/s NRZ transmission. We also confirmed that the proposed AM cancellation technique effectively reduces the transmission penalties due to frequency dithering in 10 Gbit/s NRZ data transmission performance.
