针对光纤光镊捕获颗粒时直接接触易产生机械损伤的问题,提出了一种基于光热效应的单光纤远距离捕获方法。采用功率低于20 mW的C波段光纤宽带放大自发辐射光源,实现了对中尺度二氧化硅(SiO2)小球的远距离捕获和操控,捕获距离长达800 μm。为探明该捕获机理,采用COMSOL Multiphysics有限元分析软件,仿真模拟了光纤在SiO2悬浮液不同高度位置处形成的温度场分布、对流速度场分布和粒子在溶液中的运动轨迹。研究发现,在光纤操控小球的过程中起主要作用的是热对流产生的曳力,同时调整光纤高度会改变捕获速度和捕获距离。这种光纤微流体装置结构简单、操作灵活,具备在低功率条件下大范围捕获大颗粒的条件。


To solve the mechanical damage caused by direct contact when the fiber optic tweezers captures particles, a single fiber long-distance capture method based on photothermal effect is proposed. Mesoscale silica spheres can be moved and trapped freely within 800 μm by utilizing a C-band fiber broadband amplified spontaneous emission source with a power of less than 20 mW. To find out the capture mechanism, COMSOL Multiphysics finite element analysis software is used to simulate the temperature field distribution, convective velocity field distribution, and particle motion trajectories when the fiber is at different heights in the silica suspension. It is shown that the drag force generated by the heat convection plays a crucial role in the process of the manipulation of microparticles, while the capture speed and capture distance can be changed by adjusting the fiber height. The optical fiber microfluidic device has the advantages of simple structure and flexible operation, and can realize large-scale capture of large particles by using low-power lasers.
