[0003] 1936年,RA Beth在实验上让一束圆偏振光通过细丝悬挂的半波片,首次利用光束中光子的角动量实现了物体的旋转(Beth R A. Mechanical detection and measurement of the angualarmomentum of light. Phys. Rev. , 1936, 50 :115_125)。 [0003] 1936, RA Beth in the experiment a beam of circularly polarized light passes through the filament hanging half-wave plate, the first use of the angular momentum of the photon beam to achieve a rotating object (Beth R A. Mechanical detection and measurement of the .. angualarmomentum of light Phys Rev., 1936, 50: 115_125). 自此以来人们一直在不停的探索着实现光致旋转的方法。 Since then people have been constantly exploring the light-induced rotation method. 自从1986年Askin等人提出了“光镊”实现了对粒子的三维空间控制(Ashkin, JM Dziedzic, JE Bjorkholm, S. Chu. Observation of a single-beam gradient force opticaltrap for dielectric particles. Opt. Lett. 1986, 11,288-290.),同时也促进了光致旋转的发展。 Since 1986 Askin, who put forward the "optical tweezers" to achieve a three-dimensional particle control (Ashkin, JM Dziedzic, JE Bjorkholm, S. Chu. Observation of a single-beam gradient force opticaltrap for dielectric particles. Opt. Lett. 1986, 11,288-290.), but also to promote the development of light-induced rotation. 到目前为止实现光驱动旋转主要采用如下几种方式:第一种方式是利用自旋角动量实现旋转;第二种方式是利用轨道角动量实现旋转;第三种方式是利用光的线性动量实现旋转,设计制作具有特定外形结构的微型器件,利用器件对光束的反射、折射、吸收等相互作用来实现器件的旋转(Galajda P,Ormos P.

Rotation of microscopic propellers in lasertweezers. Journal of Optics B :Quantum and Semiclassical Optics 2002,4 (2),pp. S78-S81);为了得到连续的旋转控制方式,Ormos等人根据扁平粒子被产生线偏振光的激光光镊俘获旋转后,旋转方向与偏振面方向一致,因此设计了带有横截面为十字型齿轮粒子,虽然旋转方向易控制,但是相同的条件下产生的扭转力矩较小;另外,为了获得更好的实验结果,Ormos与他的同事又提出将多个转子组合形成齿轮带动装置,利用中心转子转动带动其它转子。 [0004] Ormos group Hungarian Academy of Sciences also done a lot of research work in this area, made a variety of specially shaped rotor and verified by experiments using laser tweezers to capture and drive the rotor helical structure, comprising a propeller-shaped , helical, Sprinklers shape, through contrast experiments under the same conditions propeller-shaped rotor can achieve higher speed, lower power IOmw rotation rate may reach a few hertz (Peter Galajda, Pal Ormos. Rotation of microscopic propellers in lasertweezers. Journal of Optics B:. Quantum and Semiclassical Optics 2002,4 (2), pp S78-S81); laser in order to obtain a continuous rotary control, Ormos, who was to generate linearly polarized optical tweezers based on flat particle rotation after capture, consistent with the direction of rotation of the polarization plane direction, so the design of the cross-shaped gear with a cross section of the particles, although easy to control the direction of rotation, but torsional torque produced under the same conditions as the small; in addition, in order to obtain better results, Ormos and his colleagues suggests they be combined to form a plurality of rotor gear driven device, using a central rotor drive other rotors. 考虑到激光光镊装置的复杂性,在某些应用下使用波导光驱动更有益,尤其在微流系统中,于是他们又提出了集成系统,包括光转子,光轴和利用双光子聚合方法形成的光波导,波导光输入功率IOmw可以产生2rps旋转速率。 Given the complexity of optical tweezers apparatus waveguide optical drive to use more beneficial in some applications, particularly in microfluidic systems, so they proposed the integrated system, including optical rotor axis and is formed by a two-photon polymerization process an optical waveguide, the waveguide optical input power IOmw can produce 2rps rotation rate.
