论文摘要
我们提出了一个光力学系统，以量化一条裂片的二氧化硅光纤纤维的净力，当时激光光线被引导通过它。纤维的四个线链粘合到宏观振荡器的两侧，其运动通过米歇尔森干涉仪准确监测。激光灯通过可变的光功能和频率调制来传播。在实验上，我们发现振荡器的驱动力不仅包括从裂片的刻面中射出的光的光学力，而且还包括沿纤维引起的光纤沿着纤维的张力。净驱动力仅取决于光纤的光功率，折射率和光速，从而确定其基本起源。
We proposed an optomechanical system to quantify the net force on a strand of cleaved silica optical fiber in situ as the laser light was being guided through it. Four strands of the fiber were bond to both sides of a macroscopic oscillator, whose movements were accurately monitored by a Michelson interferometer. The laser light was propagating with variable optical powers and frequency modulations. Experimentally, we discovered that the driving force for the oscillator consisted of not only the optical force of the light exiting from the cleaved facets but also the tension along the fiber induced by the light guided therewithin. The net driving force was determined only by the optical power, refractive index of the fiber, and the speed of light, which pinpoints its fundamental origin.
