ptomechanics has witnessed its great success in detecting the gravitational waves produced by collision and merger of distant black holes or neutron stars, which confirms a major prediction of Albert Einstein’s general theory of relativity and opens an unprecedented new window on the universe. Optomechanical systems have shown their unique advantages in fundamental research as well as practical applications in high-precision metrology, signal processing, and data communication. Optomechanical devices exhibit many variations with their sizes and mechanical masses spanning orders of magnitude. Moving to the other end of the spectrum, I will talk about recent progress of nano-optomechanical devices operating in the microwave frequency regime. Fabricated on an integrated platform, they possess pico/femtogram masses and oscillate at gigahertz frequencies. These integrated devices hold great promise for many burgeoning areas in science and engineering, such as single-molecule detection, laser cooling, and quantum information processing.
Xiankai Sun received his Ph.D. degree in Applied Physics from California Institute of Technology in 2010. From 2010 to 2014, he was a Postdoctoral Associate and then an Associate Research Scientist in Department of Electrical Engineering at Yale University. In 2014, he joined Department of Electronic Engineering at the Chinese University of Hong Kong as an Assistant Professor. His current research focuses on photonic and optomechanical nanodevices for exploring new physical phenomena and developing new practical applications.
Dr. Sun was recognized by numerous professional societies, including the IEEE Photonics Society, the Photonics Society of Chinese-Americans, and SPIE (the International Society for Optics and Photonics). He was recognized as a finalist of the Blavatnik Awards for Young Scientists in 2013 by New York Academy of Sciences for his contribution to “experimental research of nanoscale optomechanical systems.” He also received the Hong Kong Research Grants Council Early Career Award in 2015. He currently serves as an Associate Editor of Optics Express.
