Research Interests

The research program in the Metamaterials and Nanophotonic Devices Lab is mainly focused on the broad area of nanophotonics, an emerging field strategically positioned at the intersection of electrical engineering, applied physics, materials science and nanoscience. We are investigating optical metamaterials, plasmonics, metasurfaces and solid-state nanophotonics to understand the interaction between light and nanoscale photonic materials and to control and manipulate these interactions at will. Our ultimate aim is to design, fabricate and characterize metamaterials and nanophotonic devices with novel optical and photonic functionalities.

Current research topics include metamaterials and metasurfaces for ocntrolling light at the subwavelength scale, plasmonic materials and devices for absorption engineering, two-dimensional materials for plasmonic and optoelectronic application, inverse design of compact millimeter wave and optical metadevices, hybrid, active and tunable nanophotonic devices based on phase transition materials.
