Abstract

L'invention concerne un système de fibre optique comprenant une fibre optique, un dispositif de couplage, et un système de génération d'un signal de pompage. La fibre optique a une biréfringence qui préserve la polarisation et un premier mode de polarisation sensiblement perpendiculaire à un deuxième mode de polarisation. Le dispositif de couplage couple un signal d'entrée avec une longueur d'onde d'entrée dans la fibre optique de telle sorte que le signal d'entrée se propage dans le premier mode de polarisation dans la fibre optique. Le système de génération d'un signal de pompage génère un signal de pompage avec une longueur d'onde de pompage comprise entre 50 à 300 nonomètres (nm) de moins que la longueur d'onde d'entrée, et contenant une première quantité de puissance de pompage suffisante pour commuter le signal d'entrée, mais pas assez suffisante pour créer des solitons d'ordre élevé. Le dispositif de couplage couple également le signal de pompage dans la fibre optique de telle sorte que le signal de pompage se propage dans le premier mode de polarisation dans la fibre optique. Le signal de pompage entraîne une biréfringence non linéaire dans la fibre optique, ce qui pousse le signal d'entrée à commuter les modes de polarisation et à se propager dans le deuxième mode de polarisation, et amplifie la propagation du signal d'entrée dans la fibre optique. Ainsi, avec le système de fibre optique, un signal d'entrée peut être amplifié et commuté simultanément, et donc des étapes séparées d'amplification et de commutation ne sont pas nécessaires.
