In this paper, a beak-shaped optical tweezer with annular core fibers is designed and studied by theoretical simulation. The finite element method is used to simulate the optical field intensity distribution of the optical tweezers, and the optical field images of the optical tweezers under different bending conditions are compared. The results show that bending deformation increases the light intensity of the side evanescent field. The Maxwell stress tensor method is used to analyze and calculate the trapping force of the optical tweezers for particles. The new tweezers are compared with the conical optical fibers to analyze the relationship between the bending radius and the trapping force, as well as between the particle radius and the trapping force. The results show that the designed optical tweezers can not only capture particles at the tip but also capture and transport particles at the side. The new optical tweezers can be applied to auxiliary research on cell biology.
