Abstract :
Summary form only given. We describe recent advances in achieving high-speed circuit latency reduction by using SOAs as both the nonlinear element and as the feedback amplifier between all-optical gates. We also describe a novel configuration of SOA based logic gates to demonstrate high-speed XOR operation. In addition, we demonstrate a novel bit level synchronisation scheme that can be used to achieve the necessary retiming to enable precise temporal processing.
