论文摘要
可以利用基于几何未结合光子晶体纤维（PCF）设计的光学波导片段作为构建块，以实现实现高级光子操作的微型复杂设备。在这里，我们展示了如何通过直接高分辨率3D打印来通过PCF设计制造光波导段，以及这些片段的组合如何实现复杂的光子设备。我们通过根据PCF制造有史以来的第一个光纤偏光束分离器来证明我们方法的前所未有的精度和灵活性。该设备在标准单模光纤的末端直接印刷，为210〜 $ $ m长，在光学电信C波段中提供宽带操作。我们的方法利用了高分辨率3D打印和PCF设计的潜力，为开发新型的微型化合物光子系统铺平了道路，这将对光学电信，传感器技术和生物医学设备产生积极影响并提高。
Optical waveguide segments based on geometrically unbound photonic crystal fibers (PCF) designs could be exploited as building blocks to realize miniaturized complex devices which implement advanced photonic operations. Here, we show how to fabricate optical waveguide segments with PCF designs by direct high-resolution 3D printing and how the combination of these segments can realise complex photonic devices. We demonstrate the unprecedented precision and flexibility of our method by fabricating the first-ever fiber polarising beam splitter based on PCFs. The device was directly printed in one step on the end-face of a standard single-mode fiber and was 210~$μ$m-long, offering broadband operation in the optical telecommunications C-band. Our approach harnesses the potential of high-resolution 3D printing and of PCF designs paving the way for the development of novel miniaturised complex photonic systems, which will positively impact and advance optical telecommunications, sensor technology, and biomedical devices.
