In this paper, we will address the benefits of the coherent detection in future optical access
networks. The scarcity of the optical spectrum, the required flexibility, and constant evolution …

demultiplexing (PolDemux) algorithm over a long-haul optical link considering the …

We propose a space-demultiplexing algorithm based on signal analysis in higher-order
Poincaré spheres for optical transmission systems supported by space-division multiplexing …

The impact of the polarization misalignment between the signal and the intercore crosstalk
(ICXT) on the performance of direct detection (DD) weakly coupled multicore fiber (WC …

We numerically investigate the polarization-mode dispersion (PMD) tolerance of Stokes

In this paper, we compare the performances of conventional CMA, two-stage CMA and
constrained CMA, from cases of fixed-point, parallelization and delay periods which are …

The high speed rotation of state of polarization (RSOP) is a key issue for 16 quadrature
amplitude modulation (QAM) coherent optical polarization division multiplexing (PDM) …

We experimentally demonstrate a flexible coherent UDWDM system with support to optical-
wireless links and adaptive DP-QPSK/DP-16QAM modulation, enabled by Stokes-based …

We present a digital technique able to monitor and compensate for the mode-dependent
losses (MDL) in space-division multiplexing (SDM) transmission systems. The working …

We propose a reduced-complexity space-demultiplexing algorithm based on higher-order
Poincaré spheres (HoPs) which is modulation format agnostic, free of training sequences …
