Abstract

We report here on the first experimental demonstration, to the best of our knowledge, of a new generation of very large mode area (VLMA) fibers intended to strengthen single-mode propagation. The originality of this work relies on an aperiodicity of the inner cladding microstructuration exacerbating the spatial rejection of higher-order-modes (HOMs) while preserving a significant confinement of the fundamental mode. The single-mode behavior was demonstrated using an optical low-coherence interferometry measurement based on the group-velocity dispersion. As suggested through a preliminary numerical approach, this outstanding characteristic/behavior is evidenced over a large spectral range spanning from 1 to 2 μm for a core diameter of 60 μm. Core scalability was also investigated.

Comparison of the computed spectral evolution of the modal overlap factor in a standard air-silica LPF (see Ref. [5]) and in the aperiodic LPF exhibiting an MFA of about 2500μm2. The solid lines represent the overlap of the FM and the dashed lines, the most confined HOM. ΔΓ represents the modal discrimination, difference between the two overlap factors. Inset, 2D refractive index profile of the two fiber structures (dark blue region, pure silica; clear blue area, index-matching passive material; red hexagons, rare-earth doped material; yellow region, air).
