The invention relates to the technical field of optical fiber mode-locked lasers, and particularly discloses a bending modulation all-optical fiber saturable absorber and a design and preparation method thereof. According to the method, controllable macroscopic bending modulation is introduced into a common single-mode optical fiber, so that linear loss caused by bending is coupled with a nonlinear Kerr effect in the optical fiber.

According to the design, the device structure in the mode-locked laser is simplified, the manufacturing cost is reduced, and the compatibility with a polarization maintaining optical fiber system is improved.
