Ji Wei

Professor Ji Wei is a faculty member at the Department of Physics, Science Faculty, National University of Singapore (NUS). He obtained his PhD from Heriot-Watt University, Edinburgh, UK, in 1986 and has since led a research group focused on nonlinear optical phenomena and ultrafast dynamics in nano-materials.

• Current research includes experimental characterization of materials using Z-scan, nonlinear transmission, and absorption spectroscopy with short laser pulses.
• Key materials under study: carbon nanotubes, semiconductor nanocrystals, 2D materials, and metal-organic frameworks (MOFs).
• Applications target next-generation photonic and optoelectronic devices, including polariton lasers and exciton-polaritonic quantum systems.

His work has resulted in over 270 publications, with an h-index above 69 (Google Scholar, July 2023). Notable contributions include the first global report on optical limiting with carbon nanotubes in 1998 and pioneering studies on MOFs for polariton lasers.

Recent article trends highlight expertise in

• exciton-polaritonic devices
• 2D materials
• quantum dots
• ultrafast spectroscopy

and applications in micro-scale lasers, photodetection, and nonlinear optical systems.

Prof. Ji’s teaching portfolio includes courses like PC2231 Modern Optics, PC4250 Advanced Analytical Techniques, and SCC3303 Computer-Aided Design for Laboratory.
