我们展示了一种低成本、高灵敏度的全光纤微悬臂梁传感器，即光纤到尖端的微悬臂梁传感器(FTMS)。在该传感器中，纳米尺寸的光纤尖端既用作微悬臂梁，又用作小型化的光探头。通过测量从共线排列的单模光纤(SMF)接收的光强度，光纤尖端悬臂梁的亚纳米位移有望被记录下来。我们发现，悬臂梁-位移曲线是由基模HE(11)在准直的SMF中引导的高斯分布所定义的。作为该技术的一个实例，FTMS振动传感器的估计分辨率为2 A。FTMS将开辟廉价光纤微悬臂梁传感的新途径。
We demonstrate a low-cost, high-sensitivity, all-fiber microcantilever sensor, a fiber-to-tip microcantilever sensor (FTMS). In this sensor, a nanosize fiber tip serves as both microcantilever and miniaturized light probe. Subnanometer displacements of the fiber-tip cantilever are expected to be registered by measuring the light intensity that it receives from a collinearly aligned single-mode fiber (SMF). We found that the cantilever-displacement curve is defined by the Gaussian profile of the fundamental mode, HE(11), guided in the aligned SMF. An FTMS vibration sensor has been implemented as an example of the technique, exhibiting an estimated resolution of 2 A. The FTMS should open new ways of inexpensive fiber-optic microcantilever sensing.
