DD-OFDM Multicore Fiber Systems Impaired by Intercore Crosstalk and Laser Phase Noise

摘要

The photodetected intercore crosstalk (ICXT) of multicore fiber (MCF) based systems employing direct-detection (DD) is characterised. The impact of the laser phase noise on the photodetected ICXT and on the performance of DD orthogonal frequency division multiplexing (OFDM) MCF-based systems is experimentally demonstrated.
