All-optical phase and amplitude regenerator for next-generation telecommunications systems

This paper demonstrating the world’s first “black box” direct phase regeneration, was a key output of the EU funded project MODE-GAP. The key contribution of Ellis’ team was the development of a novel system to generate local phase reference signals which have subsequently been used for the development of ultra-low noise amplifiers, multi-wavelength regenerators and signal processing systems for higher level modulation formats. Such advances will enable phase modulated signal qualities to be maintained along a transmission line, avoiding deleterious capacity limits in optically amplified systems, and form the subject of a subsequent Marie Curie Intra-European Fellowship.
