基于光学聚合物的集成光子器件在光学封装、生物传感和增强/虚拟现实（AR/VR）中的应用越来越受到关注。常规有机聚合物的低折射率一直是实现致密、低占用面积光子器件的障碍。报道了利用一类新型高折射率聚合物--硫族化合物无机/有机杂化聚合物（CHIP）--制备集成光子器件的方法和表征。与传统的烃基聚合物相比，该聚合物具有高折射率和较低的光损耗。这些光学聚合物通过反硫化工艺从元素硫衍生而来，这允许将廉价的单体用于这些材料。描述了一种通过光刻使用CHIP的简易制造策略，用于单模光波导、Y结分束器、多模干涉仪（MMI）和高Q因子环形谐振器，沿着器件表征。此外，在1550 nm波长附近的传播损耗为0.4 dB cm− 1，这是非氟化光学聚合物波导的最低测量损耗，同时还具有低成本材料和制造的优势。还报道了具有6 × 104量级的Q因子和45的腔精细度的环形谐振器，这是光学聚合物基环形谐振器的一些最高值。
Optical polymer‐based integrated photonic devices are gaining interest for applications in optical packaging, biosensing, and augmented/virtual reality (AR/VR). The low refractive index of conventional organic polymers has been a barrier to realizing dense, low footprint photonic devices. The fabrication and characterization of integrated photonic devices using a new class of high refractive index polymers, chalcogenide hybrid inorganic/organic polymers (CHIPs), which possess high refractive indices and lower optical losses compared to traditional hydrocarbon‐based polymers, are reported. These optical polymers are derived from elemental sulfur via the inverse vulcanization process, which allows for inexpensive monomers to be used for these materials. A facile fabrication strategy using CHIPs via lithography is described for single‐mode optical waveguides, Y junction splitters, multimode interferometers (MMIs), and high Q factor ring resonators, along with device characterization. Furthermore, propagation losses of 0.4 dB cm−1near 1550 nm wavelength, which is the lowest measured loss in non‐fluorinated optical polymer waveguides, coupled with the benefits of low cost materials and manufacturing are reported. Ring resonators with Q factor on the order of 6 × 104and cavity finesse of 45, which are some of the highest values reported for optical polymer‐based ring resonators, are also reported.
