A bend-resistant large-mode-area dual-mode photonic crystal fiber is proposed. The transmission properties are analyzed with full vector finite element method combined with perfectly matched layer boundary conditions, and the variation of bending properties with the bending radius and bending orientation angle are discussed. By optimizing the structure parameters, the fiber can only transfer the fundamental mode HE11 and second-order mode HE21 at a wavelength of 1550 nm. When the fiber is in a straight state or the bending radius is 35 cm, mode field area of the mode HE11 and HE21 are greater than 1000 mm2, and the bending loss is lower than 0.075 dB/m. Besides, the fiber can effectively inhibit the decrease of mode field area that results from the bending deformation. The minimum bending radius can reach 10 cm, and the bending orientation angle can be extended to ± 180° . The designed fiber with large mode area, low bending loss and low sensitivity of bending orientation has important applications in high power optical communication devices.
