Nanophotonic structures for extreme light-confinement interaction

Nanophotonic architectures such as photonic crystals and metamaterials have become key players in modern photonics. They offer hitherto unprecedented capabilities combined with great versatility to control various properties of light -propagation, polarization, emission and photon statistics. They have become increasingly important for chip-scale photonics. In this talk, I will present research carried out at Sandia National Labs along with my colleagues in this area using photonic crystals and metamaterials. I will discuss titanium dioxide [1] and GaN [2],[3] based photonic crystals, III-nitride nanostructures for room temperature single photon sources [4] as well as broadband light confinement and enhancement in metallic periodic structures [5].
