Metallic or dielectric nano-structures can greatly help to strengthen the interaction of materials with light and to create smaller and more efficient optical components. Almost any optical function can be accessed through the high degree of flexibility in the design and fabrication. Here, the nonlinear optical properties are of particular interest for all-optical applications. In our research group, we develop new concepts for nonlinear materials based on nanostructured and hybrid materials and study their properties and potential application. → READ MORE

Confining optical fields to extremely small volumes is one of the biggest challenge for miniaturization of optical elements to be comparable in size with electronic elements. Here, the excitation of electronic surface states on a metal-dielectric interface might open a new path for guiding light in extremely small volumes without losing the possibility of high speed operation. In our group we develop new concepts in altering the excitation and propagation of plasmonic surface states by utilizing the concept of metamaterials. → READ MORE
