"All-Dielectric Optical Metamaterials"
Jason Valentine, Mechanical Engineering
The Valentine group is focused on developing nanostructured materials with tailored electromagnetic properties at optical frequencies, specifically for applications in photovoltaics, detectors, and other more exotic devices such as invisibility cloaks. These nanostructured materials, referred to as metamaterials, can be engineered with unique optical properties due to the type of structuring and constituent materials employed. While metamaterials are typically made from structured metals, the goal for this REU is the development of novel metamaterials made entirely out of dielectrics. By avoiding metal, the optical loss can be reduced and the bandwidth of operation increased. The REU student will work closely with the PI and a graduate student on this project and be responsible for fabricating and optically characterizing dielectric metamaterials in an effort to better understand the relationship between the nanoscale structuring and the effective optical properties of the material.
Research Interest and Skills: This project is best suited for individuals with interests in nanoscale optics and materials, nanoscale fabrication, and experimental optics techniques. The individual should have completed an electromagnetics course and experience with experimental optics and spectroscopy would be beneficial.
