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 930μm2 at the straight state and 815μm2 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.
