我们展示了飞秒激光辅助二氧化硅玻璃纳米结构实现的消色差偏振旋转器。偏振面的旋转是由嵌入在多层双折射层中的光轴的手性排列引起的。在我们的实验中，我们在600-1600 nm的宽光谱范围内实现了46.0+/-0.6度和93+/-6度的旋转，甚至可以扩展到5微米。这些二氧化硅双折射光学元件显示出比液晶偏振器件或宽带晶体波片更大的优势，包括大的接受角，高的热稳定性和高的损伤阈值。(C)2015 AIP出版有限责任公司。
We demonstrate achromatic polarization rotators implemented by femtosecond laser assisted nanostructuring of silica glass. The rotation of polarization plane results from the chiral arrangement of optical axis embedded in the multi-layered stack of birefringent layers. In our experiments, we achieved rotation of 46.0 +/- 0.6 degrees and 93 +/- 6 degrees in the broad spectral range of 600-1600 nm, which can be extended even further up to 5 mu m. These silica birefringent optical components exhibit advantages over liquid crystal polarizing devices or broadband crystalline waveplates, including large acceptance angle, high thermal stability, and high damage threshold.
