Light-matter Interactions at the Semiconductor-insulator-metal Interface

Integrated photonics offer extraordinary promise for a completely new method for communication and computation, with a speed 100 times faster than electron-based technology. Silicon-based integrated photonics (SIPs), due to their compatibility with well-developed micro(nano)fabrication techniques and high refractive index contract, play a dominating role in integrated photonics industry and has demonstrated excellent performance to achieve various passive functionalities. While the potential of integrated photonics has been widely recognised by the community, the lack of active functionalities and the diffraction limited packing density hinders SIPs to reach their full potential.
In this talk, ways to implement active functionalities and increase the packing density of optical components on a chip by exploiting a special optical mode at the semiconductor-insulator-metal (SIM) interfaces will be introduced. Nanoscale lasers, signal amplifiers and photodetectors based on SIM will be explained.


Dr Ning Liu is currently a senior lecturer in nanophysics at the Department of Physics at the University of Limerick. She received her B.S. degree in Physics from the Peking University, China in 1999 and a Ph.D. degree in Condensed Matter Physics from the University of California at Irvine in 2005. Prior to joining the University of Limerick in 2013, she worked as postdoctoral research fellow in the UK, Canada, China, and Ireland. She has specialties in scanning probe microscopy and ultrafast spectroscopy and microscopy.
Her current research interests focus on nanophotonics, plasmonics and light emitting diodes. She has published 49 journal articles, including papers in Nature Nanotechnology, Nature Chemistry, Nature Materials, Light: Science & Applications, Physical Review Letters, Nano Letters, Advanced Materials, ACSPhotonics etc.
