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…

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…
