Nanophotonics and Quantum Optics
One of the most unique properties of light is that it can package information into a signal of zero mass and propagate it at the ultimate speed. It is, however, a daunting challenge to bring photonic devices to the nanometer scale because of the fundamental diffraction limit. Metamaterials can focus light down to the nanoscale and thus enable a family of new nanophotonic devices. Metamaterials, i.e. artificial materials with rationally designed geometry, composition, and arrangement of nanostructured building blocks are opening a gateway to unprecedented electromagnetic properties and functionalities that are unattainable with naturally occurring materials. The innovative field of transformation optics, which is enabled by metamaterials, inspires researchers to take a fresh look at the very foundations of optics and create a new paradigm for the science of light. Recent research focuses on refractory plamonic materials and quantum photonics.
