In recent years, terahertz systems have made significant progress both with respect to their technical specifications and to their flexibility and ease-of-use for “real-world” applications. One particularly successful approach employs optoelectronic terahertz generation, where semiconductor-based antennas convert the output of near-infrared laser light to terahertz radiation.

In this webinar, hosted by the OSA Applied Spectroscopy Technical Group, Dr. Anselm Deninger of TOPTICA Photonics AG will provide an overview of optoelectronic terahertz techniques. This includes highly precise systems for frequency-domain measurements, broadband systems for time-domain applications, as well as rapid screening systems for non-destructive testing. For each scenario, representative practical applications will be presented by Dr. Deninger.

What You Will Learn:

  • Generation and detection of pulsed and continuous-wave terahertz radiation
  • Differences between both approaches – “which should be used, and where”
  • Existing and forthcoming industrial applications of terahertz instrumentation

Who Should Attend:

  • Researchers and engineers working on, or intending to work on, terahertz technologies


Anslem Deninger, TOPTICA Photonics AG

Dr. Anselm Deninger studied physics at the University of Mainz (Germany). He obtained his PhD in 2000, having worked on the usage of laser-polarized helium-3 gas for magnetic-resonance imaging of lungs and airways. He subsequently joined TOPTICA as an R&D engineer in 2001 and helped develop TOPTICA’s first commercial cw-terahertz system in 2007. As product manager, he is responsible for TOPTICA’s terahertz product portfolio. Dr. Deninger has written or co-authored about 20 publications on terahertz technologies, including a book chapter on terahertz generation and detection with photomixers.
