In this paper,a new method of constructing single-fiber optical tweezers is proposed,which can achieve multi-optical well non-contact capture on the same optical fiber,so as to reduce the difficulty of making single-fiber optical tweez-ers and enhance the operation function of single-fiber optical tweezers.We use the 650 nm laser source to excite high purity LP11 mode in 980 nm single-mode fiber,which can achieve the multi-optical trap capture effect around the fiber port after simple micro-staggered core fusion treatment for common single-core fiber.Optical fiber ports are fabricated using thermal method to construct special tip structures.Simulation and experimental results show the feasibility of the structure.The excitation and utilization of multi-mode beams in single fiber constitute a new development of single fi-ber optical trap,enrich the function of single fiber optical tweezers,and make more practical applications in biomedi-cal research possible.
