“…Gates et al [14] have studied the propagation of modes in the LMA-based holey fibres. Abdelaziz et al [15] have designed new PCF structures, which consist of five air-holes rings, where the air-hole diameters differ from one ring to another. The others LMA structures are also known from the literature (see Refs.…”

Photonic crystal fibres with large mode areas are widely employed for reducing the impairments arising from various nonlinear effects. We suggest a new design of photonic crystal fibres with large effective mode area. The fibre consists of six air-hole rings with two different structures and unequal diameters, where the air holes of the third ring are filled with the substance having high refractive index. Employing a full vectorial finite-element method, we have found that our structure exhibits a large effective mode area (up to 3575 µm 2 at the light wavelength of 1200 nm) and low confinement losses (about 5.70×10-3 dB/km at 1550 nm).

“…Since Knight firstly proposed a LMA PCF in 1998 [5], many endeavors have been made, such as leakage channel LMA PCF [6]- [8], ring-core LMA PCF [9], [10], asymmetric structure LMA PCF [11]- [13], and so on. Nevertheless, most LMA PCF designs with low bend loss are multimode or few-mode operation at bent state [8]- [10], [12], [14], only few LMA PCFs confirm to robust SM operation conditions at bend state [6], [11], [13]. Meanwhile, many bottlenecks in the development of bend-resistant LMA PCF remain to be overcome, especially the bend distortion and the sensibility of bend orientation.…”

A rectangle lattice silica-host photonic crystal fiber with large mode area (LMA) is successfully fabricated for the first time. The introduction of rectangle lattice contributes to distinct leakage of second order modes and two large air holes provide an effective solution to suppress bend distortion. Numerical results demonstrate that a large mode field area (MFA) of 2500 μm 2 is achieved at the wavelength of 2 μm when the fiber is straight. While the fiber is bent to a radius of 30 cm, it confirms to single-mode (SM) operation conditions and the decrements of MFA at x polarization and y polarization are just 4.3% and 5%. Within a bend orientation angle of ±10 • and a wide wavelength range from 1.8 μm to 2.4 μm, the fiber can operate under single-mode (SM) conditions with low bend loss. LMA, SM operation, and small bend distortion make this fiber of great potential in developing 2 μm compact high-power fiber lasers.Index Terms-Rectangle lattice, large mode area, photonic crystal fiber, compact high-power laser.

“…Various kinds of LMA PCFs have been proposed [3][4][5][6][7][8]. However, most of them are either sensitive to bend [5,7,8] or of great difficulty to fabricate [4,6,8]. In a compact high-power laser system, a method of coiling is generally adopted to help the fiber maintain single-mode operation and create laser miniaturization.…”

In view of its feasibility for fabrication and application, a bend-resistant large-mode-area photonic crystal fiber with a triangular core is proposed. In our design, the fiber proposes a solution to the issue of bend distortion. The mode field area of the fundamental mode at the wavelength of 1.064 μm achieves 930 μm² at the straight state and 815 μm² at a bending radius of 30 cm, respectively. The decrement of the mode field area at the bend state is only 12.473% compared to the straight state. Furthermore, when the fiber is bent with a bending radius of 30 cm, numerical results demonstrate that the fiber conforms to single-mode operation conditions and the bending orientation angle can be extended to ±55°. A large mode area at bent state and low sensitivity of bending orientation make the fiber of great potential in high-power fiber lasers.
