Performance Impairments due to Inter-Core Crosstalk Dynamics in a 7-Core MCF-Based DMT-Modulated Link (STu1E.1)
Presenter: Alberto Gatto, Politecnico di Milano - DEIB

We investigate inter-core crosstalk impact on DMT-modulated signals in a 7-core fiber with different sources at the same nominal wavelength. We observe beating from relative laser frequency shift leads to time-dependent interference on DMT subcarriers.

Dynamic Crosstalk Monitoring of Real-Time Transmission in Multi-Core Fibers Based on Deep Learning (STu1E.2)
Presenter: maoqi zhang, HUST

We propose and experimentally demonstrate a novel dynamic crosstalk monitoring in multi-core fibers based on deep learning, by using asynchronous amplitude histogram (AAH). The mean absolute error (MAE) of crosstalk monitoring is below 0.78 dB.

Demonstration of Turbulence Mitigation in a 200-Gbit/s Orbital-Angular-Momentum Multiplexed Free-Space Optical Link Using Simple Power Measurements on a Probe Wavelength (STu1E.4)
Presenter: Nanzhe Hu, Uninversity of Southern California

We experimentally demonstrate turbulence mitigation in a 200-Gbit/s OAM-multiplexed free-space optical link with data channels on 1552 nm using simple power measurements on a probe wavelength of 1550 nm without interrupting the data transmission. We observe a crosstalk reduction of up to 25 dB.

Experimental Demonstration of Vortex Mode Demultiplexing Using a Concentric-Ring Transformation (STu1E.5)
Presenter: Jian Wang, Huazhong University of Science and Technology

A concentric-ring transformation method is presented to realize high-resolution sorting of vortex modes. We experimentally demonstrate the efficient demultiplexing of vortex modes with a low crosstalk <-12 dB.
