Manipulating Light with Architected Nanomaterials

Nanoscale materials have dimensions below the wavelength of light and a variety of new optical phenomena can emerge when they are arranged into architected assemblies. We apply new optical manipulation and measurement techniques to construct architected nanomaterials and explore their emergent properties. By arranging semiconducting nanomaterials nearby to metal or dielectric nanoparticles, we direct energy and electron migration to enhance light absorption or emission processes, which are fundamental to solar energy conversion and optical communications. By exploiting the architected nanomaterials to direct light flow and enhance light-matter interactions, we achieve high-performance optical cooling and sensing.
