All-optical multi-wavelength devices for ultrafast WDM signal processing

In this paper, the authors present results based on a 2R (re-amplification and re-shaping) multiwavelength regeneration system, with wavelength conversion capabilities. In a counter propagation approach, the system is able to regenerate several end user data stream at the same time opening the way to efficient wavelength allocation, network congestion reduction and QoS enhancement in the wide area optical network segment. A short review on the state of the art will be presented too.
