TL;DR: The development of the first practical ('black-box') all-optical regenerator capable of removing both phase and amplitude noise from binary phase-encoded optical communications signals is reported.
Proceedings ArticleDOI
Generation of frequency symmetric signals from a BPSK input for phase sensitive amplification
Ruwan Weerasuriya,Stylianos Sygletos,Selwan K. Ibrahim,Richard Phelan,John O'Carroll,Brian Kelly,James O'Gorman,Andrew D. Ellis +7 more
TL;DR: A novel system for simultaneous carrier recovery and frequency symmetric signals generation from a NRZ-BPSK input by exploiting FWM in HNLF for phase sensitive amplification is reported.
Proceedings ArticleDOI
All-optical phase regeneration of 40Gbit/s DPSK signals in a black-box phase sensitive amplifier
Francesca Parmigiani,Radan Slavik,Joseph Kakande,Carl Lundstrom,Martin Sjödin,Peter A. Andrekson,Ruwan Weerasuriya,Stylianos Sygletos,Andrew D. Ellis,Lars Gruner-Nielsen,Dan Jakobsen,Soren Herstrom,Richard Phelan,James O'Gorman,Adonis Bogris,Dimitris Syvridis,Sonali Dasgupta,Periklis Petropoulos,David J. Richardson +18 more
TL;DR: In this article, a black-box four-wave mixing based bitrate-flexible phase sensitive amplifier is presented. And they use it in the first demonstration of 40 Gbit/s DPSK phase regeneration.
Journal ArticleDOI
DPSK Signal Regeneration With a Dual-Pump Nondegenerate Phase-Sensitive Amplifier
P. Frascella,Stylianos Sygletos,Fatima C. Garcia Gunning,Ruwan Weerasuriya,Lars Gruner-Nielsen,Richard Phelan,James O'Gorman,Andrew D. Ellis +7 more
TL;DR: In this article, the regeneration of a 42.66-Gb/s differential phase-shift keyed signal using a dual-pump non-degenerate four-wave-mixing-based fiber-optic parametric amplifier was demonstrated.
Journal ArticleDOI
Novel real-time homodyne coherent receiver using a feed-forward based carrier extraction scheme for phase modulated signals
TL;DR: A novel real-time homodyne coherent receiver based on a DPSK optical-electrical-optical (OEO) regenerator used to extract a carrier from carrier-less phase modulated signals based on feed-forward based modulation stripping is reported.
