Abstract

We present experimental results and numerical simulations of multiple-wavelength conversion of 10 Gb/s non-return-to-zero (NRZ) signals based on 2-pumps four-wave mixing and of 40Gb/s return-to-zero (RZ) signals through supercontinuum (SC) generation in a highly nonlinear fiber (HNLF). Two pumps with a 100 GHz separation located in the region of anomalous dispersion of the HNLF were combined to form a beat signal The 10 Gb/s NRZ signal anchored on ITU grid was converted with gain into 6 new signals and 6 idlers with 100 GHz separation. High quality sc with bandwidth exceeding 50 nm was generated when the HNLF was pumped with 25 dBm average power. Sliced sc can be used as a source for all-optical multicasting.

Résumé

Nous présentons des résultats expérimentaux et des simulations numériques d’une conversion à plusieurs longueurs d’ondes des signaux 10 Gbit/s PNRZ. Cette conversion est basée sur un mélange à quatre ondes et utilise deux pompes à signaux 10 Gbit/s ou 40 Gbit/s RZ par une génération de supercontinuum (SC) dans une fibre fortement non-linéaire (HNLF). Deux pompes séparées par 100 GHz dans la région de la dispersion anomale de la HNLF sont combinées pour obtenir un battement du signal. Le signal 10 Gbit/s PNRZ fixé sur le peigne ITU était converti avec amplification à 6 signaux et 6 fréquences-images avec séparation de 100 GHz. Un SC de haute qualité avec une bande spectrale de plus de 50 nm a été généré quand une puissance moyenne de 25 dBm a été appliquée sur la HNLF. Le SC spectralement tranché peut être utilisé comme une source pour une diffusion groupée tout-optique.
