Abstract: |
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 tweezers 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 fiber optical trap, enrich the function of single fiber optical tweezers, and make more practical applications in biomedical research possible. |
