Division of Spectroscopy: visible, infrared, terahertz

Research Topics

  • Optical investigations of novel materials in the visible, infrared, and terahertz regimes
  • Low-dimensional semiconductor structures: quantum wells, heterostructures, superlattices, quantum dots, graphene and other twodimensional semiconductors, topological insulators
  • Dynamical processes on femtosecond and picosecond time scales
  • Semiconductor electrons and excitons in strong terahertz fields
  • Terahertz emitters and detectors
  • Ultrafast optoelectronic components
  • Development of III-V nanowires using molecular beam epitaxy.

Characterization Methods

  • Terahertz time-domain spectroscopy
  • Nonlinear laser spectroscopy, pump-probe, four-wave mixing
  • FTIR spectroscopy
  • Raman spectroscopy
  • Photoluminescence, electroluminescence
  • Time-resolved photoluminescence
  • Infrared near-field microscopy

Time-resolved optical experiments are performed with table-top femtosecond lasers (Ti:sapphire oscillators, amplifiers, OPG/OPA, THz emitters) and with the free-electron laser at ELBE. The latter offers unique possibilities for time-resolved spectroscopy in the mid- and far-infrared regimes, in particular for investigations on semiconductors and their nanostructures. Synchronization of table-top femtosecond lasers to the free-electron laser is also possible (e. g, for two-color experiments). The division is also involved in the application of these measurement techniques at the Dresden High Magnetic Field Laboratory.
