Bend-resistant leaky multi-trench fiber with large mode area and single-mode operation. [PDF]
PLoS ONE, 2018 A novel structure of modified multi-trench fiber (MTF) with characteristics of bend-resistance and large mode-area is proposed. In this structure, each low refractive-index trench of traditional MTF is broken by two gaps up and down.

Large mode area double-layer all-solid anti-resonant fiber for high-power fiber lasers
Results in Physics, 2021 A novel double-layer all-solid anti-resonant fiber (DL-AAF) is proposed to develop large mode area (LMA) fiber for high-power fiber laser applications. Single-mode property and mode field area scaling are investigated in simulations.

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 Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
Photonics, 2022 We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

Structure and propagation of modes of large mode area holey fibers [PDF]
Optics Express, 2004 We report cross-section measurement and propagation measurement of modes of large mode area holey fibers using near-field scanning optical microscopy (NSOM). Mode profiles are measured at the fiber end face using a scanning optical fiber tip held 10 nm from the surface, and compared to theoretical models.

Narrow-Linewidth Diffraction-Limited Tapered Er-Doped Fiber Amplifier with 2 mJ Pulse Energy
Photonics, 2022 The possibility to scale-up output pulse energy in diffraction-limited Er-doped fiber amplifier has been studied. It is shown that the utilization of tapered fiber design allows one to increase the pulse energy up to 2 mJ, while keeping the diffraction ...
