Reconfigurable Spatial-Mode-Selective Frequency Conversion in a Three-Mode Fiber
TL;DR: In this article, a scheme for spatialmode-selective frequency conversion in a few-mode fiber was proposed and the upconversion of arbitrary superpositions of LP01 and LP11a signal modes from C-band to S-band with all conversion efficiencies within 1 dB range of one another.
Proceedings ArticleDOI
Phase-encoded signal regeneration exploiting phase sensitive amplification
David J. Richardson,Radan Slavik,Joseph Kakande,Francesca Parmigiani,Adonis Bogris,Dimitris Syvridis,Periklis Petropoulos +6 more
TL;DR: In this article, the authors discuss recent advances in phase sensitive amplification technology and review its application to the regeneration of multi-level phase-encoded signals, and discuss the application of phase-sensitive amplification to phase-decoded signals.
Proceedings ArticleDOI
Transmission performance of phase-preserving amplitude regenerator based on optical injection locking
Liam Jones,Francesca Parmigiani,V.J.F. Rancaño,Mohamed A. Ettabib,Periklis Petropoulos,David J. Richardson +5 more
TL;DR: The phase-to-amplitude noise redistribution of a 10Gbit/s BPSK signal in a phase-preserving amplitude regenerator based on optical injection locking is experimentally investigated and its performance in a transmission experiment over an installed fiber link is demonstrated.
Proceedings ArticleDOI
Mode-Selective Frequency Conversion in a Three-Mode Fiber
TL;DR: In this paper, a scheme for spatial-mode-selective frequency conversion in a few-mode fiber was proposed and the upconversion of two signal modes from C-band to fundamental mode in S-band with crosstalk below −15.5 dB was demonstrated.
Proceedings ArticleDOI
Temporal multiplexing of complex modulation formats facilitated by their coherent optical superposition
TL;DR: In this paper, passive coherent optical addition of complex modulation formats using delay line interferometers to increase their bits per symbol and, thus, their spectral efficiency has been investigated and two possible applications are demonstrated as examples.
