Polarizing very-large-mode-area bragg fiber

2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011
Single-mode larger-mode-area (LMA) all-glass (free of air-holes) fibers are required for all-fiber high-power lasers and amplifiers as they allow for efficient splicing with other components, which is impossible in the case of LMA photonic crystal fiber. Recently, we have demonstrated an active all-glass Bragg fiber with a mode-field diameter of 26 µm (

Very Large Mode Area Pixelated Bragg Fibers

Workshop on Specialty Optical Fibers and Their Applications, 2015
Generalized half-wave-stack condition combined with well-chosen hetero-structured cladding is used to design and realize scalable single-mode pixelated Bragg fibers with mode field diameter as large as 60 μm.

Design of large mode area, mode selection fiber

SPIE Proceedings, 2014
The paper study on the effect of index distribution on the mode field and calculated the mode distribution in various index profiles. A single mode gaussian hybrid multicore fiber with 19 hexagonally arranged high index quartz rods is designed and investigated. Theoretical and simulative results are presented and compared to the conventional large mode

Ultra large mode area pixelated Bragg fiber

SPIE Proceedings, 2016
We report on the design and the fabrication of a new design of an all-solid Bragg fiber based on the pixelization and heterostructuration of a cladding made of only two high index rings. The thickness of the low index ring as well as the geometry of the heterostructuration (its symmetry and the number of removed pixels) have been chosen to maximize the

Measuring the Modal Content of Large-Mode-Area Fibers

IEEE Journal of Selected Topics in Quantum Electronics, 2009
Spatially and spectrally resolved imaging of mode content in fibers, or more simply, S2 imaging, is a new measurement technique for analyzing the mode content of large-mode-area (LMA) fibers. It works by spatially resolving the spectral interference that occurs when light in a few-mode fibers scatters into different modes that then propagate with ...

Parasitic Modes in Large Mode Area Microstructured Fibers

OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007
We present experimental evidence for parasitic modes guided by both bandgap and low density of state effects in large mode area silica microstructured fibers and explore ways of minimizing their presence via the fiber geometry.
