LIU Hong

Dr. Liu Hong is currently a Principal Scientist II at Institute of Materials Research and Engineering (IMRE), Agency for Science, Technology and Research (A*STAR), Singapore. He holds an adjunct appointment of Associate Professor atthe Department of Materials Science and Engineering (MSE), National University of Singapore (NUS). He obtained his Master of Engineering and PhD degrees from the Dept of Mechanical Engineering, NUS. He joined Singapore Institute of Manufacturing Technology (SIMTech), A*STAR in 2001 and moved to IMRE in 2003. Prior to his current appointment, Dr. Liu Hong assumed the appointment as the Head of the Nanofabrication Department (NFB) at IMRE from January 2019 to Jan 2024.

Research Interests

My research focuses on the study of the fundamental light-matter interactions at subwavelength scale and potential applications such as next-generation neuromorphic photonics, quantum light sources and flat optical components. Leveraging the well-established capabilities of design, simulation, nanofabrication and state-of-the-art characterization, we have investigated the optical resonators interactions with light altered by the size, shape, assembly and dimensionality to realize extreme control and manipulation of light’ properties at nano-meter scale. Complex and hybrid photonic structures have been realized by the advanced top-down and bottom-up fabrication techniques to achieve high Q-factors and efficiency, which enable us to tackle the challenging issues towards real applications. My research interests include nonlinear meta-optics, nanoplasmonics, advanced nanopatterning techniques and scaling-up nanomanufacturing technologies.
