low transmission penalty dual stage broadband discrete Raman Amplifier
Optics Express, 2018Co-Authors: Lukasz Krzczanowicz, Asif Iqbal, Ian Phillips, Pavel Skvortcov, Paul Harper, W ForysiakAbstract:We present a broadband (>70nm), dual stage, discrete Raman Amplifier designed with small and standard core fibres to maximize gain and minimize nonlinearity. The Amplifier provides ~19.5dB net gain, 22.5dBm saturation output power and a noise figure of <7.2dB. 120Gb/s DP-QPSK transmission over 38x80km at a pre-FEC BER <3.8x10−3 is demonstrated.

performance improvement of broadband distributed Raman Amplifier using bidirectional pumping with first and dual order forward pumps
International Conference on Transparent Optical Networks, 2016Co-Authors: Asif Iqbal, Paul Harpe, Giuseppe R Martella, Francesca Gallazzi, Juan Diego AniacastanoAbstract:In this paper, a new bidirectional pumping scheme with dual order forward pumps is proposed. Performance is compared numerically with conventional bidirectional and backward only pumping schemes for a 70 nm bandwidth, 61.5 km distributed Raman Amplifier. We demonstrate that it is possible to design a flat gain spectrum with improved noise figure and OSNR, as well as a low gain ripple (< 1 dB).

Impact of pump-signal overlap in S+C+L band discrete Raman Amplifiers
'The Optical Society', 2020Co-Authors: Iqbal, Md Asif, Ia Phillips, Krzczanowicz Lukasz, Harpe Paul, Di Rosa Gabriele, Richte André, Forysiak WladekAbstract:We experimentally investigate the impact of pump-signal overlap in ultra-wideband (>13THz) Raman Amplifiers and measure the transmission penalty on 30GBaud PM-QPSK signals due to adjacent Raman pumps in a 15dB gain, 150nm (∼18.8THz) S+C+L-band discrete Raman Amplifier. We present an efficient numerical model to predict the performance penalty induced by crosstalk from Rayleigh backscattered light from backward-propagating Raman pumps showing good agreement with the experimental results. A 4nm guard-band must be retained around an overlapping Raman pump based on typical, commercial semiconductor laser pump diodes to ensure a negligible transmission penalty in S-ban
