Large mode area fibers with asymmetric bend compensation
Optics Express, 2011 Fibers with asymmetrical bend compensation offer to completely remove the tradeoff between mode area and single-modedness, with potentially huge impact on high-power amplification. These fibers would be difficult to fabricate, but are the only fundamental-mode strategy that can remove the bend-distortion limitations on mode-area scaling.

Large-mode-area multicore fibers in the single-moded regime
Optics Express, 2011 The effectively single-mode regime is analyzed for a class of large mode area multicore fibers. The performance tradeoff between bend loss, single-modedness, and mode area for these fibers is shown to be at best equivalent to step-index fiber.
