Research Fellows

Dr Lavery's research at UCL focuses on mitigation of nonlinear interference in long-haul transmission over optical fibre, ultradense wavelength-division multiplexing for passive optical networks, coherent-enabled advanced modulation formats, and digital signal processing for optical communications. Within UNLOC, Dom is mainly involved in the second research theme by developing DSP for optical communications, and fourth research theme by assisting or conducting experimental investigation of theoretical techniques.

Yaroslav Prylepskiy is a postdoctoral Research Fellow at the Aston Institute of Photonic Technologies. His main areas of research include (i) NFT-based optical transmission, methods, optimization, including optical formats and extentions of "eigenvalue communications", lumped and distributed amplification; periodic NFT method, (ii)soliton usage for telecommunications, soliton-noise interference, spectral efficiency for soliton-based transmission, (iii)numerical methods for fast NFT signal decomposition, and (iv) spectral efficiency and capacity bounds for the optical fibre links. Within UNLOC, Yaroslav is working on RT1 with current current activities focused on (i) evaluation of capacity limits for the soliton-based transmission, (ii) mutual information evaluation for the soliton-based transmission, (iii) generalisation of the NFT-based approach, nonlinear inverse synthesis, and (iv) numerical methods for fast NFT processing.

  Yaroslav used to play piano and compose some relatively weird poetry (in Russian). The current Russian minister of Economics Alexey Ulyukaev mentioned him as one of his favourite Russian poets. He is also an NBA and LeBron James fan. Yaroslav likes the English Premier League but has recently ceased to support Chelsea.

Mingming's principal research interest lies in long-haul/unrepeatered coherent transmissions system optimisation using advanced Raman fibre laser based amplification techniques. Within UNLOC, his work focuses on RT4 and experimental investigation of quasi-lossless Raman transmission link using advanced Raman fibre laser (RFL) based amplification techniques, in order to improve the transmission performance and satisfy the link requirement simultaneously for different nonlinearity compensation techniques.
