Polarization Dependent Loss (PDL) is expected to severely impact next-generation optical systems. It is a non-unitary effect that reduces the benefit of multiplexing in polarization in terms of channel capacity. In this presentation, I will present the associated loss of capacity and then provide solutions, both at the transmitter and at the receiver, that offer a resilience to this effect.
Arnaud Dumenil was born in Besançon, France in 1991. He received his Engineering Diploma from Centrale Marseille and a MSc in Telecommunications from DTU, Denmark, both in 2016. He then received a PhD degree in May 2020 from the Institut Polytechnique de Paris, in strong collaboration with Nokia Bell Labs in France. His thesis addressed optical communications with non-unitary effects. He just started a post-doctoral research at the ETIS laboratory focusing on short-blocklength error correcting codes for IoT applications.
