报告题目： Novel Nanophotonic Structures, Devices, and Circuits for Enhanced Light–Matter Interaction
Nanophotonics studies light generation, detection, and manipulation at the nanoscale. Photonics as a field began with the invention of the laser in 1960, with other following developments including the laser diode in the 1970s, optical fiber for data transmission, and the erbium-doped fiber amplifier. These inventions formed the basis for the telecommunications revolution of the late 20th century and provided the infrastructure for the Internet. With the development of nanotechnology, photonics has now entered into the nano regime, covering a huge range of science and technology applications including computation and communication, biological and chemical sensing, medical diagnostics and therapy, and 3D display technology, etc. In this talk, I will introduce several novel nanophotonic devices recently investigated in my research group. By exploiting the light–matter interaction in an untraditional material or in an unconventionally designed nanostructure, those devices are shown to achieve new functionalities or exhibit exceptional performance enhancement compared with their traditional counterparts. They hold great promise for many burgeoning areas in science and engineering, such as single-molecule detection, laser cooling, and information processing.
Xiankai Sun received his Ph.D. degree in Applied Physics from California Institute of Technology in 2010, where his doctoral thesis focused on nanophotonics, optoelectronics, semiconductor lasers, and hybrid electronics/photonics integration. From 2010 to 2014, he was a Postdoctoral Associate and then an Associate Research Scientist in Department of Electrical Engineering at Yale University, where he developed novel nano-optomechanical resonators for studying the interaction of photonics, mechanics, and microwaves on a chip. 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 and an Editorial Board Member of Scientific Reports.
