Biographical Information

Hong Liu joined the A*STAR Institute of Materials Research and Engineering (A*STAR IMRE) in 2003 and has been leading the institute’s Intelligent Nano-optics (INO) Group since 2020. The INO Group is primarily dedicated to the study of the fundamental light-matter interactions at the subwavelength scale and potential applications such as next-generation neuromorphic photonics, quantum light sources and flat optical components. Leveraging A*STAR IMRE’s well-established capabilities of design, simulation, nanofabrication and state-of-the-art characterisation, the INO Group has investigated the interactions of optical resonators with light to realise extreme control and manipulation of light’s properties at the nanoscale. Currently, he is leading a team under National Semiconductor Technology and Innovation Center (NSTIC) to develop nanoimprint lithography technology for scaling up of flat optics.
