In this work we optimize the design of coherently-combined multicore fiber amplifiers. It has been shown that increasing the number of cores in such fibers helps to increase the combinable output power. However, in counter-pumped multicore fibers, th

Publikováno v: Fiber Lasers XVII: Technology and Systems.

In this work we present theoretical investigations of the power scaling potential of multicore fibers. In principle it is widely accepted that increasing the number of active cores helps to overcome current challenges such as transversal mode instabi

Efficient parameter identification for macroscopic fiber orientation models with experimental data and a mechanistic fiber simulation

Autor: Tim A. Osswald, Armin Kech, Donald G. Baird, Gregory M. Lambert, Susanne K. Kugler, Camilo Cruz

Publikováno v: AIP Conference Proceedings.

Advanced macroscopic fiber orientation models depend on a variety of phenomenological parameters. The prediction quality is closely related to the choice of those parameters. Therefore, the aim of this research is to propose an efficient method for p

Publikováno v: Results in Physics, Vol 28, Iss, Pp 104626-(2021)

The influence of twist-induced effect on the performance of anisotropic optical fiber is investigated theoretically and numerically. First, we study the light propagation in the twisted optical fiber with twist-induced mechanical stress using the ana

Simplified bead-chain model for direct fiber simulation in viscous flow

Publikováno v: Journal of Non-Newtonian Fluid Mechanics. 250:52-58

For efficient simulation of the motion of fibers during processing of fiber-reinforced thermoplastics, we propose a simplification of the bead-chain model (BCM), in which each fiber is modeled as a chain of spheres. The proposed simplified bead-chain

Journal of Composites Science; Volume 2; Issue 1; Pages: 2

Compression molding of long fiber reinforced composites offers specific advantages in automotive applications due to the high strength to weight ratio, the comparably low tooling costs and short cycle times. However, the manufacturing process of long
