Since the introduction of coherent transponders, forward error correction based on soft
decision is now established in optical communication. In this paper, we give a tutorial-style …

Imbalances between the four sampling channels of a coherent detector with polarization
diversity can rapidly degrade system performance. One of these imbalances, namely the …

We report on the generation and the transmission of 1-Tb/s superchannels for long-haul
optical systems. Based on a multicarrier approach, we optimize the design of coherent …

A vision of the photonic network in 2020 is presented, which envisages a “smart photonic
cloud.” A smart photonic cloud is defined as a universal network platform without any …
