Multicore fiber delay line performance against bending and twisting effects

TL;DR

This paper experimentally investigates how bending and twisting affect multicore fiber performance, showing that twisting significantly reduces group delay fluctuations caused by bending.

Contribution

It provides new experimental insights into how twisting can mitigate bending-induced delays in multicore fibers.

Findings

Twisting reduces group delay fluctuations in bent multicore fibers.

Bending causes measurable signal propagation issues.

Twisting improves fiber stability under bending conditions.

Abstract

We report the experimental evaluation of bending and twisting effects on the propagation and radiofrequency signal processing performance of multicore fibers. We demonstrate that twisting minimizes to a large extend the group delay fluctuations over a bent multicore fiber.
