Characteristics of Collimators Based on the Large-Mode-Area CMCF for Coupling Laser Beam

Applied Sciences, 2021
A new collimator based on a homemade concentric multilayer-core fiber (CMCF) is proposed and experimentally demonstrated. This collimator was fabricated using a tail fiber with large mode area and single-mode operation.

A Detailed Study of a Resonant-Assisted Segmented Cladding Fiber for Large Mode Area Applications

Photonics
In this work, we have proposed and optimized a large mode area segmented cladding fiber (SCF) with an unconventional low-index segment cladding. The low-refractive-index cladding proposed in this paper consists of three parts.

Large-mode-area multicore fibers in the single-moded regime

Optics Express, 2011
The effectively single-mode regime is analyzed for a class of large mode area multicore fibers. The performance tradeoff between bend loss, single-modedness, and mode area for these fibers is shown to be at best equivalent to step-index fiber.

All Solid Multistep-Index Core Large Mode Area Single-Mode Fiber

IEEE Photonics Journal
In this paper, a large-mode-area (LMA) single-mode fiber based on multistep-index core structure is proposed. The multistep-index core increases the mode field area (MFA).

Modeling of transverse mode interaction in large-mode-area fiber amplifiers

Optics Express, 2008
We model the transverse mode interaction in a large-mode-area fiber amplifier by solving the Fresnel wave equation including local gain saturation. In order to calculate the electric field distribution we apply a finite difference beam propagation method, which is followed by the derivation of the modal powers and modal polarization states.
