Description

This research opportunity involves the exploration of light-matter interactions with the aim of optimizing optical characteristics through the understanding of constituent material properties and design of nano-to-micro scale structures. In particular, we seek to create novel optical responses through the geometry, orientation, and/or arrangement of sub-wavelength features.   For instance, the nanostructured surface morphology found in the moth eye has inspired structured antireflection coatings, and singly negative metamaterials have been utilized to demonstrate exceptional reflectance from a nanopillar array.  The central focus of the research will be to exploit the light-matter interactions offered by these nano-to-micro scoped structures within a broad range of topical areas: metasurfaces, composite nanostructures, transformation optics, high-index nanoresonators, metamaterial cloaking, surface wave, anisotropic metamaterials, sub-diffractive photonics, biomimetic metasurfaces, and/or gradient index materials. Emphasis will be placed upon all-dielectric (i.e., non-metallic) metamaterials designs which have recently shown promise in a wide variety of applications such as nanoresonators, anisotropic metamaterials, laser optics, and zero-index metamaterials. Additionally, this opportunity will require multidisciplinary communication skills to interface with several fields including chemistry, optics, solid-state physics, photorefractives, and crystal growth.  Resources for this research will include access to state-of-the-art additive manufacturing facilities, clean room capabilities, optical characterization facilities with femtosecond pulse to continuous wave sources, and comprehensive materials characterization facilities.
