Sorokina, Mariia, Sergeyev, Sergey and Turitsyn, Sergei (2019). Fiber echo state network analogue for high-bandwidth dual-quadrature signal processing. Optics Express, 27 (3), pp. 2387-2395.


All-optical platforms for recurrent neural networks can offer higher computational speed and energy efficiency. To produce a major advance in comparison with currently available digital signal processing methods, the new system would need to have high bandwidth and operate both signal quadratures (power and phase). Here we propose a fiber echo state network analogue (FESNA) — the first optical technology that provides both high (beyond previous limits) bandwidth and dual-quadrature signal processing. We demonstrate applicability of the designed system for prediction tasks and for the mitigation of distortions in optical communication systems with multilevel dual-quadrature encoded signals.
