Gabriele Liga

Gabriele Liga

Gabriele is interested in understanding optical fibre transmission bottlenecks and harnessing communication theory techniques to mitigate them. He focuses on detection theory, nonlinear equalization techniques, modulation, coding and modeling of the optical fibre channel. Within UNLOC, Gabriele is involved in RT1 (detection strategies tailored to the nonlinear fibre channel) and RT2 (practical performance limits of digital backpropagation).

Nikita Shevchenko

Nikita Shevchenko

Nikita's main research interests lie in fundamental understanding and theoretical investigation of (i) information capacity bounds of the nonlinear optical fibre channels, (ii) solitons in optical communications, and (iii) optical transmission based on the nonlinear Fourier transform (NLFT). He is currently working within RT1 of UNLOC investigating:

  • validation of the GN-model for nonlinear channel capacity estimation
  • developing analytical bounds on capacity of the nonlinear optical fibre channel
  • detection strategies for the soliton-based coherent transmission system

Mohammad Al-Khateeb

Mohammad Al-Khateeb

Mohammad's research focuses on optical fibre nonlinearity compensation and capacity extension techniques in long haul optical transmission systems. The research describes the potential and limitations of All-optical nonlinearity compensation techniques (Optical Phase Conjugation) and digital compensation techniques (signal processing). He is currently involved in RT1 and RT2 and working on: (i) validating and analysing noise evolution in nonlinearity compensated optical transmission systems, (ii) developing experimental setup for optical phase conjugators, and (iii) analysing multi-OPC systems and considerations when using such nonlinearity compensation technique.
