Nano-Photonics: Plasmonics, Hyperbolic Metamaterials and Applications in Thermophotonic Devices

Nano-photonics or nano-optics is the study of light at the nanoscale where light-matter interaction gives rise to exotic novel phenomena. The entire filed of nano-optics have generated tremendous interest in recent years for their potential applications in energy conversion, catalysis, photonic computing and other applications.

Our interest in nano-photonics is to develop efficient (low loss and tunable) plasmonic materials, metamaterials, and devices for applications in light-trapping, catalysis and energy conversion applications. Our current projects include hot electron based photo-electrochemical reactions, development of low loss plasmonic materials and high temperature plasmonic devices.
