Crosstalk Impacts on Homogeneous Weakly-Coupled Multicore Fiber Based IM/DD System

We numerically discussed crosstalk impacts on homogeneous weakly-coupled multicore fiber based intensity modulation/direct-detection (IM/DD) systems taking into account mean crosstalk power fluctuation, walk-off between cores, laser frequency offset, and laser linewidth.Comment: 3 pages, 11 figures

Spectrum Superposition Based Chromatic Dispersion Estimation for Digital Coherent Receivers

We propose and experimentally demonstrate a fast blind CD estimation method based on signal spectrum superposition. With only 4096 samples, a maximum estimation error of 0.25% of the accumulated CD for 7 x 112 Gbps DP-QPSK WDM signal is verified
