Stability investigation of bi-directional single-fiber reconfigurable transparent WDM ring network

Not Accessible

Future efficient and flexible WDM ring network will require dynamic channel re-configuration and channel rerouting to bypass a traffic blocking or network failure. A bidirectional network operating on a single fiber and insensitive to amplifier gain transients caused by the variation of channel load will answer both demands. In general bidirectional operation has been achieved skipping optical amplifiers or with poor performance in linear-optical amplifiers. In fact optical amplifier bidirectional operation in a closed loop needs to remove all isolating elements and therefore devices may strongly interplay and even generates lasing action and chaotic behavior [1], Gain stabilization issues were also not solved and only very recently suitable performance of optical-gain-clamped (OGC) erbium-doped waveguide amplifier (EDWA) was achieved [2] allowing gain stabilized bi-directional operation along a close loop.
