Dramatic increase in the bandwidth of optical fiber inline polarizer can be achieved by using metal nano-grid on the fiber tip. However, high extinction ratio of such fiber polarizer requires high spatial frequency metal nano girds with high aspect ratio on the small area of optical fiber tip. We report the development of a nano-fabrication process on the optical fiber tip, and the design and realization of the first ultra-wideband fiber inline polarization device with Au nano gird fabricated on a single mode optical fiber end face.
通过在光纤尖端使用金属纳米网格，可以显著提高光纤在线偏振器的带宽。然而，这种光纤偏振器的高消光比要求在光纤尖端的小面积上具有高纵横比的高空间频率金属纳米网格。我们报道了一种在光纤尖端的纳米制造工艺的发展，以及在单模光纤端面上制造的具有金纳米网格的首个超宽带光纤在线偏振装置的设计与实现。
