Abstract: Since its demonstration on early days that femtosecond laser was utilized as a tool to prototype real three-dimensional structures, femtosecond laser direct writing (FsLDW) has been attracting more and more research interest and efforts. Depending on materials, its fabrication resolution reached several tens of nanometers. For transparent materials, three-dimensional structures could be readily designed and fabricated. What is more attractive is the technology is applicable to various materials from polymers, transparent solids, semiconductors, metals, and ceramics. Various micro-nanosctructures and devices varying from micro-optics, micro-electronics, micro-mechanics, and microfluidics, to sensors, optoelectronics, biomimetics and biophotonics have exhibited, mainly based on two-photon induced photopolymerizatin technology. For practical industrial application, the capability of device fabrication from hard processing materials is more important. Significant progress has been achieved through ten year work in our lab along this line. In this talk, I will introduce our research on fabrication micro-photonic and optical devices using diamond, sapphire, lithium niobate and silica. Excellent optical performances have been achieved from these devices.

Biography: Sun Hongbo, currently the Changjiang-Scholar professor of optical engineering at Tsinghua University, China. He received the B.S. and the PhD degrees in electronics from Jilin University, Changchun, China, in 1992 and 1996, respectively. He worked as a postdoctoral researcher in Satellite Venture Business Laboratory, the University of Tokushima, Japan, from 1996 to 2000, and then as an assistant professor in Department of Applied Physics, Osaka University, Japan. In 2004, he was promoted as a full professor (Changjiang Scholar) in Jilin University, and since 2017 he has been working in Tsinghua University, China. His research interests have been focused on ultrafast optoelectronics, particularly on laser nanofabrication and ultrafast spectroscopy: Fabrication of various micro-optical, microelectronical, micromechanical, micro-optoelectronic, microfluidic components and their integrated systems at nanoscale, and exploring ultrafast dynamics of photons, electrons, phonons, and surface plasmons in solar cells, organic light-emitting devices and low-dimensional quantum systems at femtosecond timescale. So far, he has published over 400 scientific papers in the above fields, which have been cited for more than 12000 times according to ISI search report. He is currently the topical editor of Optics Letters (OSA), Light: Science and Applications (Nature Publishing Group), Chinese Science Bulletin (Springer), and editorial advisory board member of Nanoscale (RSC) and Display and Imaging (Old City Publishing). He is IEEE, OSA, SPIE, and COS fellow.
