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.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

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.

Large Pitch Photonic Quasi-Crystal Fiber Amplifier
IEEE Photonics Journal, 2012 We design an ytterbium-doped large pitch photonic quasi-crystal fiber (PQF) for amplifying high-energy ultrashort laser pulses. The proposed fiber exhibits unique properties such as very large mode area (4660 μm2), less attenuation (0.42 dB/km ...
