Lei Xu is an Associate Professor at Department of Engineering in School of Science & Technology. He is a member of the Advanced Optics and Photonics Group (www.aoplab.com)

Career overview

Dr Lei Xu obtained his PhD (2014) in Optics from Nankai University, China. Since then, he has been performing research and engineering activities in different universities: Nankai University, The Australian National University and the University of New South Wales. His research interests are linear and nonlinear nanophotonics, optoelectronics meta-devices, nanostructure-enabled low-carbon technologies (i.e. solar energy harvesting), and bio-photonics.

Before joining NTU, Lei worked as:

  • Research Fellow (2018 -2020), University of New South Wales and Australian National University, Australia

  • Visiting Fellow (2016 -  2017), Research School of Physics, Australian National University, Australia
  • Postdoctoral Fellow (2014 - 2016), College of Electronic Information and Optical Engineering, Nankai University, China

Research areas

My research focuses on investigating light-matter interactions using resonant meta-structures, specifically manipulating electromagnetic fields at subwavelength scales through optically induced electric and magnetic multipolar resonances, with a specific focus on three primary directions:

  • Energy harvesting technologies: development of a specialised resonant meta-optical system tailored for energy conversion applications, solar cell enhancement, and the advancement of up-conversion infrared imaging technologies. Flat optical devices using metasurfaces, contributing to future advanced nanotechnology solutions.
  • Bio-Photonics: design and development of functional meta-optical systems purpose-built for bio-sensing applications and wearable sensors, contributing to the fields of healthcare and biotechnology, improvements in diagnostics, and monitoring capabilities via optical meta-devices.
  • Tuneable and reconfigurable Meta-devices: Advancing ultra-thin and lightweight optical metadevices to replace conventional bulky optical components, enabling novel approaches to precision light manipulation for high-quality imaging, transmission, and recognition applications.
