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

## TL;DR

This paper investigates how crosstalk affects the performance of IM/DD systems using homogeneous weakly-coupled multicore fibers, considering factors like power fluctuation, core walk-off, and laser characteristics.

## Contribution

It provides a numerical analysis of crosstalk impacts in multicore fiber IM/DD systems, incorporating various realistic factors affecting system performance.

## Key findings

- Laser linewidth and frequency offset affect crosstalk impact.

## Abstract

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.
