The research department Fiber Photonics targets basic and application-oriented research in the field of fiber-based photonics with a focus on life and environmental sciences. Speciality and hybrid fiber waveguides are investigated with regard to light generation and sensing properties, using materials and photonic concepts that are innovative and traditionally not used in fiber optics, while they enable a significantly extension of the application domain.
The work concentrates on fundamental aspects and application-related questions of light-matter interaction and its possible applications in the field of biophotonics with a focus on nonlinear light generation, high-power lasers and detection and analysis of single biologically relevant nanoobjects by means of elastic light scattering within microstructured fibers. Furthermore, plasmon-active nanostructures on fiber end surfaces, fiber-based optical tweezers and novel hollow core fiber concepts are investigated.
On the basis of the Europe-wide unique infrastructure, fiber optics research at IPHT has allowed to demonstrate new physical effects and open up new fields of applications, especially in the field of biophotonics.
