AI总结:

本文提出一种可重复制备超高透射光学纳米光纤的方法,基模透射率达99.95%,损耗改善两个数量级,高阶模透射率提高300%以上,并强调拉制前清洁度对性能的关键作用。

摘要:

我们提出了一种可重复制备超高透射光学纳米光纤(直径530 nm,拉伸长度84 mm)的方法,其单模透射率为99.95 ± 0.02%,归一化到整个拉伸长度时,对应于2.6 × 10⁻⁵ dB/mm的拉锥损耗。当在195 mm拉伸长度的光纤上可控地激发下一族高阶模式时,我们实现了97.8 ± 2.8%的透射率,归一化到整个拉伸长度时,拉锥损耗为5.0 × 10⁻⁴ dB/mm。我们的拉制和转移程序使我们能够在高真空条件下制备透射功率超过400 mW的光学纳米光纤。这些结果作为参数发表在我们先前的工作中,当遵循本文详述的协议时,基模损耗改善了两个数量级,高阶模透射率提高了300%以上。我们从拉制过程中的透射率提取了唯一的基模发射频谱图,该频谱图不包括非对称模式的激发;这与未遵循我们清洁协议的拉制过程形成鲜明对比。这些结果关键取决于拉制前的清洁度,当正确遵循我们的拉制协议时,与模拟结果高度一致。

英文摘要:

We present a procedure for reproducibly fabricating ultrahigh transmission optical nanofibers (530 nm diameter and 84 mm stretch) with single-mode transmissions of 99.95 $ \pm$ 0.02%, which represents a loss from tapering of 2.6 $\,\times \,$ 10$^{-5}$ dB/mm when normalized to the entire stretch. When controllably launching the next family of higher-order modes on a fiber with 195 mm stretch, we achieve a transmission of 97.8 $\pm$ 2.8%, which has a loss from tapering of 5.0 $\,\times \,$ 10$^{-4}$ dB/mm when normalized to the entire stretch. Our pulling and transfer procedures allow us to fabricate optical nanofibers that transmit more than 400 mW in high vacuum conditions. These results, published as parameters in our previous work, present an improvement of two orders of magnitude less loss for the fundamental mode and an increase in transmission of more than 300% for higher-order modes, when following the protocols detailed in this paper. We extract from the transmission during the pull, the only reported spectrogram of a fundamental mode launch that does not include excitation to asymmetric modes; in stark contrast to a pull in which our cleaning protocol is not followed. These results depend critically on the pre-pull cleanliness and when properly following our pulling protocols are in excellent agreement with simulations.
