Abstract
This talk will discuss recent work on optical phenomena and photonic devices made from 2D chalcogenides (e.g., halide perovskites and carbon nanotubes) as well as 1D excitonic semiconductors. I will present how 1D nanostructuring of excitonic 2D semiconductors into nanophotonic dielectric gratings can enable exploration of new regimes of light-matter confinement including formation of hybrid exciton-plasmon-polariton states. This discussion will be extended to superlattices which are scalable over large areas. Further we will show that the light-matter hybridization persists in emission of direct gap 2D semiconductors such as hybrid halide pervoskites. Finally I will present our recent work on nanotubes and show dynamic tunability of their optical properties. I will conclude by giving a broad perspective on future prospects of 2D materials from fundamental science to applications.
