Structure and propagation of modes of large mode area holey fibers [PDF]

Optics Express, 2004
We report cross-section measurement and propagation measurement of modes of large mode area holey fibers using near-field scanning optical microscopy (NSOM). Mode profiles are measured at the fiber end face using a scanning optical fiber tip held 10 nm from the surface, and compared to theoretical models.

A Large Mode Area Parabolic-Profile Core Fiber with Modified Segmented in Cladding

Photonics, 2022
In this paper, a novel fiber with a parabolic-profile core and eight segmented trenches in cladding is designed. The designed fiber consists of the segmented trench of low refractive index in cladding and parabolic-profile of high refractive index in the

Bend-resistant leaky multi-trench fiber with large mode area and single-mode operation. [PDF]

PLoS ONE, 2018
A novel structure of modified multi-trench fiber (MTF) with characteristics of bend-resistance and large mode-area is proposed. In this structure, each low refractive-index trench of traditional MTF is broken by two gaps up and down.

Influence of Pedestal Fiber Splice on Tm-Doped Fiber Laser Performance

IEEE Photonics Journal, 2023
The influence of Tm-doped pedestal fiber splice on the output performance of a large-mode-area (LMA) Tm-doped fiber laser (TDFL) has been investigated. Arc-fusion induced refractive-index deformation leads to laser leakage from the core to the pedestal ...

Large Mode Area Fibers for High Power Applications [PDF]

Optical Fiber Technology, 1999
We review our recent work toward designing large mode area fibers for high power applications. We show that appropriately designed doped multi-mode fibers can be used to provide robust single-mode output when used in fiber laser cavities. Single-mode (SM) fiber mode field diameters of ~35µm are demonstrated with record SM pulse energies of 0.5mJ at ...

Large-mode-area multicore Yb-doped fiber for an efficient high power 976 nm laser.

Optics Express, 2021
We present an efficient 976 nm laser generation from an ytterbium (Yb)-doped step-index multicore fiber (MCF) with six cores placed in a ring shape. Each of the six cores has a large-mode-area (LMA) and a low numerical aperture (NA), which makes the MCF ...

Segmented Cladding Fiber With a High-Index Ring in Core for Wideband Single-Mode Operation in Any Bending Orientation

IEEE Photonics Journal, 2021
A resonant-ring-assisted large mode area segmented cladding fiber (RR-SCF) with a high-index ring in the core is proposed. Numerical investigations of the effects of the high-index ring on the leakage losses of guiding modes, mode area, and electric ...
