We believe we report the first demonstration of dual-cavity optical automatic gain control (OAGC). The dual-cavity technique results in improved stability of the amplifier gain spectrum under pump and signal power variations as compared to conventional OAGC.
We study transient power excursions of an all-optically gain-controlled amplifier chain. We observe that the speed of residual power excursions increase much faster with the of amplifiers than uncontrolled networks.
