Recently, experts from the University of Science and Technology of China collaborated with experts from the University of Maryland School of Medicine and the Southwest University of Science and Technology to propose a new optical mode—a one-dimensional Bloch surface that exists in a multilayer dielectric film and a nanofiber composite structure. Wave, and using this model, successfully solved the technical problem that the ultrafine polymer nanofiber could not transmit optical signals on a conventional substrate.

As we all know, the huge achievements of micron-scale fiber have created a highly developed Internet industry and a rapidly "smaller" world. Therefore, the basic theory of micro-fibers won the 2009 Nobel Prize in Physics. Today, nanoscale fiber optics has become a hot topic in international research. Polymer nanofibers are one of the first choices for building ultra-compact photonic devices and miniaturized integrated photonic circuits due to their good mechanical properties, especially their flexibility and flexibility, and their ability to change the properties of their materials through chemical design.
However, the material is flexible and has a large aspect ratio. It must be placed on a substrate, such as a commonly used glass or silicon wafer, to be practical, to develop a novel nano-optical waveguide sensor device, etc., while the nano-fiber radius is small, for example, less than 125 nm. When placed, the nanofibers placed on the glass will not be able to transmit optical signals.
In order to solve this problem, the research team carefully designed the multilayer dielectric film to support the polymer nanofiber by using structural parameters, and blocked the optical signal leakage in the nanofiber by the photonic band gap of the multilayer film. The experimental results show that the ultra-fine nanofiber can transmit optical signals completely on the multilayer dielectric film.
According to reports, the research work was supported by the Ministry of Science and Technology, the National Natural Science Foundation of China, the Energy Chemistry Collaborative Innovation Center, and the Anhui Outstanding Youth Fund. The related sample production process was supported by the instrument and technical support of the Micro-Nano Research and Manufacturing Center of the University of Science and Technology of China.
