Efficient bending compensation of large mode area fiber

SPIE Proceedings, 2014
While much research has been developed to achieve very large mode areas (LMA) fibers, many difficulties arise, such as bending losses, mode deformation, and high order modes suppression. The main obstacle which remains difficult to confront in LMA fibers is bending distortion.

High-power very large mode-area thulium-doped fiber laser

Optics Letters, 2012
Large-pitch photonic-crystal fibers have demonstrated their unique capability of combining very large mode areas, high output powers and robust single-mode operation at a wavelength of 1 μm. In this Letter, we present the experimental realization of thulium-doped very large mode-area fibers based on the large-pitch fibers with record mode-field ...

Demonstration of bend-induced nonlinearities in large-mode-area fibers

Optics Letters, 2007
We present what we believe to be the first direct measurements of enhanced nonlinearities in large-mode-area fibers due to bend induced reductions in effective area. Both Raman scattering and self-phase modulation are observed to increase in tightly coiled fibers.

Bend distortion in large mode area fiber amplifiers

OECC/ACOFT 2008 - Joint Conference of the Opto-Electronics and Communications Conference and the Australian Conference on Optical Fibre Technology, 2008
As ever larger mode area fibers are designed and incorporated into high-power amplifiers, bend-induced mode distortion becomes an important limitation. In any reasonable coiled-fiber arrangement, bend distortion can reduce mode area, gain interaction, and suppression of higher-order modes.
