Large mode area pixelated trench fiber [PDF]

Advanced Photonics, 2014
We propose a novel fiber that offers excellent suppression of higher-order-modes with loss higher than 10dB/m and low loss for fundamental mode (

Large-mode-area leaky optical fiber fabricated by MCVD [PDF]

Applied Optics, 2011
A large-mode-area single-mode optical fiber based on leaky-mode filtering was prepared by a modified chemical vapor deposition (MCVD) technique. The fiber has a leaky cladding that discriminates the fundamental mode from higher-order modes. A preliminary version has a 25 μm core diameter and 0.11 numerical aperture. A Gaussian-like mode with 22 μm mode

Bendable large-mode-area fiber with a non-circular core [PDF]

Applied Optics, 2018
We investigate mode-area-scaling and bending performances of a Yb-doped large-mode-area fiber with an elongated non-circular core. Such fiber can be bent in the plane of its short axis to suppress bending effects, such as mode area reduction and mode profile distortion.

Large-mode-area soliton fiber oscillator mode-locked using NPE in an all-PM self-stabilized interferometer. [PDF]

Applied Optics, 2022
In this work, we investigate an approach to scale up the output pulse energy in an all-polarization-maintaining 17.3 MHz Yb-doped fiber oscillator via implementation of a 25 µm core-diameter large-mode-area fiber.

Large mode-area all-solid anti-resonant fiber based on chalcogenide glass for mid-infrared transmission.

Optics Express, 2023
A large mode-area chalcogenide all-solid anti-resonant fiber has been designed and successfully prepared for the first time. The numerical results show that the high-order mode extinction ratio of the designed fiber can reach 6000, and the maximum mode ...

Experimental investigation of quasi-static mode degradation in a high power large mode area fiber amplifier.

Optics Express, 2021
In this work, quasi-static mode degradation in high power fiber amplifiers has been investigated experimentally. An increase of M2 from 1.3 to 2.6 with distortion of the beam profile is observed, which results in the signal spectra and backward light ...
