Topic: "3D nanoprinted optical fiber sensors"

^Abstract

Material and structure of the optical fiber used for optical communication are relatively single and it cannot meet the increasing requirements of various optical fiber sensing applications. Optical fiber microstructured sensors combine the advantages of optical fiber and microstructure and it has become a hot research area in recent years. Femtosecond laser induced two-photon polymerization is a maskless and 3D nanoprinting method. In this presentation, I will introduce our recent research progress in 3D nanoprinted optical fiber sensors including MEMS and micro-optics. Femtosecond laser 3D nanoprinting method can significantly improve the performance of optical fiber sensors in both material and structure.
