Tunable chiroptical response in metamaterial-nanocrystal hybrid systems
Abstract
Tailored interactions between light emitters and nanophotonic antennas are essential to realizing new applications ranging from quantum computing to light harvesting to non-reciprocal light propagation. The overall objective of this project is to understand and control light emission from colloidal nanocrystals coupled to chiral plasmonic metamaterials, and therefore to understand nanoscale light-matter interactions in electromagnetic environments of unusual symmetry. Specifically this project will examine the polarization and decay rates of nanocrystal emitters near chiral plasmonic structures in three different configurations, ranging from dilute nanocrystal films to patterned quantum dot solids to specifically targeted and localized individual nanocrystals. The first objective will focus on the development of tunable and switchable chiroptical systems by combining emitters with reconfigurable metamaterials. The second objective will focus on controlling the properties of single emitting nanocrystals in chiral electromagnetic environments. The third objective will create nanocrystal solids that form an integral part of the chiral structure to study the nature of off-resonant interactions between nanocrystals and chiral plasmonic structures.
