University of Southampton researchers have developed a data transmission system that could benefit optical communications networks by eliminating phase noise from optical amplifiers and cross talk induced by rogue signals. Southampton researchers, working on the European Union's PHASORS project, developed a phase sensitive amplifier and phase regenerator for high-speed binary phase-encoded signals, which eliminates phase noise directly without the need for conversion to an electronic signal.

"This result is an important first step towards the practical implementation of all-optical signal processing of phase-encoded signals, which are now being exploited commercially due to their improved data-carrying capacity relative to conventional amplitude coding schemes," says PHASORS director David Richardson.

Richardson says the technology also could be used in test and measurement applications in science and engineering, optical sensing, and metrology.
