我们进行了一个试点试验的高度方便的锥度制造全氟渐变折射率聚合物光纤。代替传统的外部加热，我们利用高功率传播光（在本实验中为500 mW）引起的内部加热。聚合物纤维的约4 mm长的部分是锥形的，并且围绕其中点的约2 mm长的腰部的外径约为200 µm，其非常均匀，标准偏差为4.3 µm。通过这种技术制造的聚合物光纤锥被证明是能够产生倏逝波，从而测量液体的折射率从1.333到1.410。
We perform a pilot trial of the highly convenient taper fabrication of perfluorinated graded-index polymer optical fibers. Instead of conventional external heating, we utilize internal heating caused by high-power propagating light (500 mW in this experiment). An approximately 4-mm-long section of a polymer fiber is tapered, and the outer diameter of the ∼2-mm-long waist around its midpoint is approximately 200 µm, which is quite uniform with a standard deviation of 4.3 µm. The polymer fiber taper fabricated by this technique is shown to be capable of generating evanescent waves and thus measuring the refractive indices of liquids from 1.333 to 1.410.
