Polarization-maintaining and single-mode large mode area pixelated Bragg fiber.

Optics Letters, 2020
This Letter reports on a large mode area pixelated Bragg fiber in which some high refractive index rods were replaced by boron-doped rods that allows polarization maintaining behavior while keeping single-mode behavior. The realized all-solid fiber has a

High absorption large-mode area step-index fiber for tandem-pumped high-brightness high-power lasers

, 2020
A short absorption length ytterbium (Yb)-doped large-mode area (LMA) fiber is presented as a step forward to mitigate the stern problem of nonlinear scatterings in a tandem pumping scheme adopted for high-power fiber laser.

Circular gradient-diameter photonic crystal fiber with large mode area and low bending loss.

Journal of The Optical Society of America A-optics Image Science and Vision, 2019
In this paper, a silica-based sixfold circular gradient-diameter photonic crystal fiber (CGPCF) with five rings is proposed, and the matching conditions of air hole lattices are established considering the gradient and diameter of the air holes.

Bend resistant large mode area fiber with step-index core and single trench

Optical fiber technology (Print), 2019
A novel bend resistant large mode area fiber with step-index core and single trench in the cladding is proposed. Numerical results demonstrate that the largest effective mode area reaches up to 2460 μm2 at the wavelength of 2 μm when the bend radius is ...

Single-mode large-mode-area Er–Yb fibers with core based on phosphorosilicate glass highly doped with fluorine

OPTO, 2019
Single-mode Er–Yb fibers with the core based on a phosphorosilicate glass matrix (up to 6.5 mol.% P2O5) highly doped with fluorine (up to 0.9 wt.%) were fabricated using an all-gas-phase modified chemical vapor deposition method.
