纤端光操纵:光镊·光手·光枪

Specialty Optical Fibers for Micro Particle Manipulation:Optical Tweezers,Hands and Gun

自1986年光镊技术被发现以来,光的力学效应的研究与应用成为了光学研究中的一个重要分支。不同于传统的显微镜构造的光镊平台,基于环形芯光纤的光镊为更多维的粒子操纵提供了方便,并能使得显微系统与操纵系统分开来。光镊能实现对粒子的捕获,但如果要进一步地对粒子的姿态进行操纵,就需要基于多芯光纤的光学微光手,而如果想要将捕获粒子发射出去,就需要基于同轴双波导光纤的光枪。介绍了基于不同种类光纤的光镊、光手和光枪的设计以及它们对粒子的操控效果。

Since the optical tweezers technology was discovered in 1986,the study and application of the mechanical effect of light has become an important branch of optical research.Unlike conventional microscope-configured optical tweezers platforms,optical tweezers based on ring-core fibers offer the convenience of more dimensional particle manipulation and separate the microscopic system from the manipulation system.The optical tweezers can capture particles,but if you want to further manipulate the particle’s attitude,you need an optical micro-optic hand based on a multi-core fiber.If you want to emit the captured particles,you need an optical gun based on a coaxial dual-waveguide fiber.This article mainly introduces the design of optical tweezers,optical hands and optical guns based on different kinds of optical fibers and their manipulation effects on particles.
