Abstract
This paper proposes and demonstrates an all-optical subcarrier label swapping subsystem with 2R (reamplification, reshaping) optical regeneration and wavelength conversion. The experimental results show error-free operation with reshaping and regeneration leading to negative power penalty for signals with impaired signal-to-noise and extinction ratios. While the experiment was conducted on a single wavelength channel, a multiwavelength optical label switching system can incorporate this technique in parallel. The 2R regeneration in the all-optical label-swapping subsystem implies its viability in a scalable optical-label switching network.
