Abstract:

Fast processing of information by cost-effective and compact devices is central to modern society. Light is considered to be the frontrunner to take over some of these tasks traditionally implemented by electronics, which is becoming too slow, bulky and energy-consuming. This requires strong light-matter interactions that plasmonic structures, based on metals, can efficiently supply more than any other platform by confining the electromagnetic field to sub-wavelength regions. Nonetheless, many fundamental issues regarding Kerr nonlinear plasmonic nanostructures remain controversial or open. I will discuss our recent progress on the figure-of-merit for the ultimate performance, the fundamental limitations and novel approaches to improve the performance, and the advantages of plasmonic platforms over all-dielectric ones.

Short Bio:

Dr. Guangyuan Li earned a PhD degree from Peking University, China. He worked as a Postdoctoral Fellow at Peking University and at Nanyang Technological University, respectively. He was the PI for several nationally competitive grants in China, including the National Science Foundation of China (NSFC), and won the Outstanding Postdoctoral Fellow of Peking University in 2012. He is now working on nonlinear plasmonics with CUDOS, the University of Sydney. His expertise is mainly in Plasmonics and Metamaterials, especially in waveguides, gratings, sensors, nano-lasers, and nonlinear nanophotonics. He has authored or co-authored more than 30 journal papers in Nature Communication, Laser & Photonics Reviews, Scientific Report, et al. He is also an active reviewers for IOP, OSA and IEEE journals on photonics.
