Optical fibers provide an ideal base for novel photonic devices due to their unique optical properties, outperforming the properties of planar waveguides in many cases. The Department Fiber Photonics at the Leibniz Institute of Photonic Technology (IPHT), a team of highly motivated specialists concentrates on implementing and using novel optical concepts in various areas of photonics, mainly in nonlinear optics, biosensing, hollow core waveguides and ultrafast fiber-integrated metasurfaces. Currently we are focusing on nonlinear light generation in liquid core fibers, providing mid-IR radiation with exceptionally high coherence, on the tracking of freely diffusing nano-objects with sizes <10nm inside fibers and on the development of sophisticated hollow core waveguides.The group is located at the IPHT in Jena and has a Europe-wide outstanding infrastructure to facilitate nano- and microstructured optical fibers. We work very close together with the photonics people from the local university and from industry.

Research areas

Prof. Schmidt currently focusses his research on nano-photonic optical fibers by placing nano- and microstructured elements into and onto fibers and using these hybrid multimaterial devices in various areas of optics, mainly in biophotonics. Current research interests include:

  • coherent nonlinear light generation at mid-IR wavelength
  • Biosensing (e.g. tracking of nano objects in fiber)
  • propagation of light in novel fiber structures (e.g. hollow core and metamaterial fibers)
  • optical metamaterials and metasurfaces

Teaching fields

Prof. Schmidt's teaching is devoted to the early involvement of young developing scientists in state-of-the-art research. Currently, he holds two courses in:

  • Fiber optics
  • Active Photonic Devices

Research methods

The infrastructure at the Leibniz Institute of Photonic Technology and the laboratories led by Prof. Schmidt offer a wide range of methods for the fabrication and characterization of all kinds of optical fibers, including:

  • broadband mid-IR ultrashort pulse lasers
  • fiber-drawing tower and lithography technology
  • pressure-assisted melt infiltration
  • scanning optical near-field microscopy
  • various spectrometers, transmission setup, lasers and other light sources
