FUNCTIONAL PHOTONIC NANOSTRUCTURES

Research_Staude_please_add_a_captionThe Functional Photonic Nanostructures junior research group at the Institute of Applied Physics is dedicated to the study of the fundamental optical properties and potential applications of subwavelength nanoparticles supporting localized optical resonances. Resonant nanoparticles and their assemblies can show complex and often surprising interactions with light, giving rise to phenomena such as "magnetic light", directional scattering, and strong near-field enhancements. Using the capabilities of modern nanotechnology, these interactions can be tailored by the size, shape, material composition, and arrangement of the nanoparticles. As such, resonant nanoparticle structures are a versatile research platform for investigating fundamental light-matter interactions and nanoscale coupling phenomena. Furthermore, they provide unique optical functionalities opening new opportunities for applications like next-generation (quantum) light sources, truly flat optical components, and optical communications. In the Functional Photonic Nanostructures junior research group we combine top-down and bottom-up nanofabrication approaches to experimentally realize composite photonic systems able to control the emission, propagation, and absorption of light and all of its properties at the nanoscale, and we use a range of dedicated techniques for their optical characterization.
