Geometric Shaping of 2-Dimensional Constellations in the Presence of Laser Phase Noise
Hubert Dzieciol, Gabriele Liga, Eric Sillekens +2
In this paper, we propose a geometric shaping (GS) strategy to design 8, 16, 32 and 64-ary modulation formats for the optical fibre channel impaired by both additive white Gaussian…
Modulation Format Dependent, Closed-Form Formula for Estimating Nonlinear Interference in S+C+L Band Systems
Daniel Semrau, Lidia Galdino, Eric Sillekens +3
A closed-form formula for the nonlinear interference estimation of arbitrary modulation formats in ultra-wideband transmission systems is presented. Enabled by the proposed approac…
Experimental Investigation of Deep Learning for Digital Signal Processing in Short Reach Optical Fiber Communications
Boris Karanov, Mathieu Chagnon, Vahid Aref +4
We investigate methods for experimental performance enhancement of auto-encoders based on a recurrent neural network (RNN) for communication over dispersive nonlinear channels. In…
Optical Fiber Communication Systems Based on End-to-End Deep Learning
Boris Karanov, Mathieu Chagnon, Vahid Aref +3
We investigate end-to-end optimized optical transmission systems based on feedforward or bidirectional recurrent neural networks (BRNN) and deep learning. In particular, we report…
SWIFT: Scalable Ultra-Wideband Sub-Nanosecond Wavelength Switching for Data Centre Networks
Thomas Gerard, Christopher Parsonson, Zacharaya Shabka +3
We propose a time-multiplexed DS-DBR/SOA-gated system to deliver low-power fast tuning across S-/C-/L-bands. Sub-ns switching is demonstrated, supporting 12250 GHz channels…
Packet Timescale Wavelength Switching Enabled by Regression Optimisation
Thomas Gerard, Hubert Dzieciol, Joshua Benjamin +5
A linear regression algorithm is applied to a digital-supermode distributed Bragg reflector laser to optimise wavelength switching times. The algorithm uses the output of a digital…
