dc.description.abstractThe goal of this research is to control light-matter interactions in three levels of hierarchical robust photonic systems: individual and assembled nanostructures, individual local assemblies and coupled local assemblies. Specifically, controlled optical properties of individual nanostructures such as emission/absorption peak position and photoluminescence intensity are investigated via the selection of materials and dimensions. In addition, spatial arrangements of assembled nanostructures are examined to see the effect on the degree of light amplification/attenuation and real refractive index which are important variables for the design of novel photonic systems that obey parity-time symmetry. Finally, manipulation of optical activity of local assemblies including cavity modes, emission output and mode splitting are investigated by altering coupling strength between assemblies, localized gain/loss contrast and arrangement of engineered defects.
