Optical Systems

Our research focusses on the development of optical systems, their physical foundations and their applications. In particular we are interested in:

  • Spectroscopic methods and instrumentation for planetary research, astronomy and Earth observation: Terahertz (THz) heterodyne spectroscopy, Laser-induced breakdown spectroscopy (LIBS), Raman spectroscopy
  • THz imaging and spectroscopy for applications in security
  • Time-resolved and high-resolution semiconductor spectroscopy
  • THz lasers: THz silicon lasers, optical systems based on quantum-cascade lasers
  • Superconducting detectors and related physics: hot electron bolometric mixers, superconducting single photon detectors


Book: Terahertz Techniques

Research and development in the terahertz portion of the electromagnetic spectrum has expanded very rapidly during the past fifteen years due to major advances in sources, detectors and instrumentation. Many scientists and engineers are entering the field and this volume offers a comprehensive and integrated treatment of all aspects of terahertz technology. The three authors, who have been active researchers in this region over a number of years, have designed Terahertz Techniques to be both a general introduction to the subject and a definitive reference resource for all those involved in this exciting research area.
