The PHASORS project targets the development and applications of fibre based phase sensitive amplifier (PSA) technology in 40Gbit/s broadband core networks, and seeks to provide Europe with a lead in this important yet relatively unexplored area. PSAs have the potential to be a disruptive technology within future optical communications enabling ultra-low noise amplifiers and a host of important ultrafast optical processing functions for networks employing high spectral efficiency phase encoded signals.
