Topic

Synthetic Interface Optics: Plasmonic/dielectric, TMDC and van der Waals Metasurfaces

 

Abstract

Metasurfaces and low-dimensional materials have been developing as two important candidates in the interfacial engineering, providing a plethora of new possibilities in novel optoelectronic functions and applications. The synergies between those two domains hold great promises in manipulating light-matter interaction. In this talk, I will start from reviewing and reporting some of the most recent developments in plasmonic and dielectric metasurfaces, and then focus on how monolayer TMDC and layered 2D materials could be hybridized with classic metasurfaces to modulate and structure novel light behavior, such as zero-dark-current and bipolar semimetal photodetector, monolayer  meta-lens of atomic thickness, hybrid designs with enhanced SHG, PL, and tunable structural colors, by the coordinated hybridization between those two parties. Finally, we will elaborate our new breakthrough on van der Waals polaritonic metasurfaces, as a new roadmap toward ultra-low loss, long-range propagation, topological interfaces, and tailorable on-chip integrated functional devices.
