The working group concentrates on basic as well as application-oriented questions of light-matter interaction on the basis of hybrid fibers and their application in the fields of biophotonics, life sciences and sensing technology. Hybrid fibers represent a new type of optical fiber, which includes sophisticated materials or photonic elements such to unlock physical effects or applications accessible for fiber optics that were previously inaccessible for fiber optics. Examples of applications lie within fields of nonlinear light generation in optofluidic fibers, single virus detection, plasmonic near-field probes, bioanalytics, meta-surfaces, optofluidic sensors and novel microstructured hollow core fiber structures for waveguiding in hitherto unused spectral domains such as the ultraviolet and the mid-infrared.
- Non-linear light generation using optofluidic fibers
- Detection and trapping of single diffusing micro- and/or nanoobjects in fibers or at the end face
- End face functionalization with nanostructures (e.g. metasurfaces)
- Hollow core fibers and waveguides
- Microstructured fibers, photonic crystal fibers, light cages
The access to the mentioned research topics is mainly provided by the unique infrastructure and expertise available at Leibniz-IPHT in the field of fiber optics and biophotonics, aiming to identify new physical effects and open up new fields of application.
Areas of application
- Highly coherent light sources in a variety of spectral ranges (UV, VIS, NIR, MIR)
- Bioanalytics and -sensing (e.g. analysis of single biologically relevant nano-objects in aqueous solution)
- Functionalized fiber end faces (e.g. coupling into fibers at extremely high angles)
- Fiber Integrated Spectroscopy
- Near-field microscopy
