Research:

In the Valentine group we are developing optical metamaterials which are nanostructured composites that allow one to engineer optical properties at will. In our group we are exploring both metal-based (plasmonic) metamaterials as well as low-loss all-dielectric variants. On a fundamental level, we use the engineering freedom associated with nano-scale structuring to realize and investigate optical properties that don’t exist in nature such as a negative and zero-index of refraction. On a more applied level, we are using metamaterials to realize novel device applications such as ultra-compact optical elements, efficient and low power optoelectronics, and hot electron-based energy conversion devices.
