Advanced nanostructure fabrication based on FIB and transfer

Nanooptics is a field where nanostructures are used to engineer the light in proximity of the nanostructures for the purpose of manipulating or enhancing light-matter interactions at nanoscale, improving resolution and sensitivity of optical microscopy, and modulating the properties of propagating light waves. Therefore, nanostructures play an essential role in this field. While dedicated to his research in nanooptics, Dr. Xiaofei Wu, a senior scientist of Leibniz IPHT since 2021, has developed quite some unique and outstanding nanostructure fabrication techniques to solve the fabrication challenges for different projects in the last 15 years. In this talk, Xiaofei will present several examples of fabrication of different nanostructures to showcase the versatility of these techniques. Although Xiaofei’s experience in nanofabrication involves various techniques including focused ion beam (FIB), electron beam lithography, 3D laser nanoprinting, nanoimprinting, etc., this talk will mainly focus on the ones based on FIB and pre- and post-transfer, complementing other established and mainly electron-lithography-based fabrication capabilities. The aim of this talk is to introduce Xiaofei’s expertise in nanofabrication, and thus to inspire ideas of application of these techniques in our existing or future research projects.

Dr. Xiaofei Wu is a Senior Scientist in Leibniz Institute of Photonic Technology. He received his PhD in optics at Peking University, China, in 2010. Before coming to Jena and joining Leibniz-IPHT in 2021, he did postdoctoral research at University of Würzburg, Max Planck Institute for Solid State Research and University of Bayreuth. Dr. Wu is an experimentalist in the area of nano-optics, and his current research interests focus on optical properties of metallic nanostructures and their applications in optical techniques, and their fabrication techniques as well.
