采用拉丝法拉制出直径为200 nm的硫系（As（2）S（3））纳米纤维，成功地嵌入到SU8聚合物中，形成了具有光滑解理端面的片上波导和高Q值微结谐振器（Q = 3.9 × 104）。谐振腔的谐振调谐是通过局域激光辐照实现的。在一个7厘米长的片上硫族化物波导中实现了带宽为500 nm的强超连续谱产生。我们的结果提供了一种方法，紧凑，高光学质量，和强大的光子器件的发展。
Chalcogenide (As(2)S(3)) nanofibers as narrow as 200 nm in diameter are drawn by the fiber pulling method, are successfully embedded in SU8 polymer, and form on-chip waveguides and high-Q microknot resonators (Q = 3.9 × 10(4)) with smooth cleaved end faces. Resonance tuning of resonators is realized by localized laser irradiation. Strong supercontinuum generation with a bandwidth of 500 nm is achieved in a 7-cm-long on-chip chalcogenide waveguide. Our result provides a method for the development of compact, high-optical-quality, and robust photonic devices.
