Recent advances in multi-band amplification support ultra-wideband (UWB) systems as a suitable solution to cope with the increasing fiber communications traffic demand. The combination of UWB with …
The tight channel filtering imposed by long cascades of reconfigurable optical add-drop multiplexers (ROADMs) represents, nowadays, one of the major performance-limiting aspects for optically-route…
Ultrawide-bandwidth (UWB) optical amplification covering C+L bands over 102 nm is implemented by using a seamless semiconductor optical amplifier (SOA) as a high-power booster with a maximum output…
We report on the use of semiconductor optical amplifiers (SOAs) to extend the optical bandwidth of next generation optical systems to 100 nm and beyond. After discussing the technological progress …
