Un schéma de multiplexage de phase entièrement optique pour les signaux modulés en phase est proposé et démontré expérimentalement en utilisant un mélange à quatre ondes (FWM) dans une fibre hautement non linéaire (HNLF). Il a été démontré expérimentalement que deux signaux de multiplexage par répartition en longueur d'onde (WDM) à modulation par déplacement de phase différentielle (DPSK) décalés π/10 de 2 Gb/s sont convertis et multiplexés en phase en une modulation par déplacement de phase en quadrature différentielle à 20 Gb/s. (DQPSK) avec les formats de non-retour à zéro (NRZ) et de retour à zéro (RZ), respectivement. Les résultats expérimentaux montrent que, en raison de l'effet de doublement de la profondeur de modulation de phase et de l'effet de multiplexage de phase dans le processus FWM, un signal DQPSK est généré avec succès grâce au multiplexage de phase entièrement optique proposé avec une sensibilité du récepteur et une efficacité spectrale améliorées.

Abstract: An all-optical phase multiplexing scheme for phase-modulated signals is proposed and experimentally demonstrated using four-wave mixing (FWM) in a highly-nonlinear fiber (HNLF). Two 10-Gb/s π/2-shifted differential phase-shift keying (DPSK) wavelength-division multiplexing (WDM) signals are experimentally demonstrated to be converted and phase-multiplexed into a 20-Gb/s differential quadrature phase-shift keying (DQPSK) signal with non-return-to-zero (NRZ) and return-to-zero (RZ) formats, respectively. Experimental results show that, due to phase-modulation-depth doubling effect and phase multiplexing effect in the FWM process, a DQPSK signal is successfully generated through the proposed all-optical phase multiplexing with improved receiver sensitivity and spectral efficiency.
