SUMMARY:Low-dimensional and van der Waals Meta-photonics - Prof. Cheng-Wei

DESCRIPTION:<b>Abstract</b>\nMetasurfaces and low-dimensional materials ha
 ve been developing as two important candidates in the interfacial engineer
 ing\, providing a plethora of new possibilities in novel optoelectronic fu
 nctions and applications. The synergies between those two domains hold gre
 at promises in manipulating light-matter interaction. In this talk\, I wi
 ll start from reviewing and reporting some of the most recent developments
  in plasmonic and dielectric metasurfaces\, and then focus on how monolaye
 r TMDC and layered 2D materials could be hybridized with classic metasurfa
 ces to modulate and structure novel light behavior\, such as zero-dark-cur
 rent and bipolar semimetal photodetector\, monolayer  meta-lens of atomic
  thickness\, hybrid designs with enhanced SHG\, PL\, and tunable structura
 l colors\, by the coordinated hybridization between those two parties. Fin
 ally\, we will elaborate our new breakthrough on van der Waals polaritonic
  metasurfaces\, as a new roadmap toward ultra-low loss\, long-range propag
 ation\, topological interfaces\, and tailorable on-chip integrated functio
 nal devices.\n\n<b>Biography</b>\nProf. Cheng-Wei Qiu was appointed Dean
 ’s Chair Professor twice (2017-2020 & 2020-2023) in College of Design an
 d Engineering\, NUS. He was Fellow of Optica\, SPIE and The Electromagneti
 cs Academy\, US. He is well known for his research in structured light and
  interfaces. He has published over 460 peer-reviewed journal papers. He wa
 s the recipient of the SUMMA Graduate Fellowship in Advanced Electromagnet
