Over the last 20 years, thin and lightweight optical elements have become very desirable,
especially for the terahertz (THz) range. Reduction of the volume of optical elements …

Within the last decade, photoconductive terahertz (THz) systems have become well-
established tools in scientific laboratories and industrial R&D departments. In particular, the …

We carried out an experimental comparison study of the two most established optoelectronic
emitters for continuous-wave (cw) terahertz generation: a uni-traveling-carrier photodiode …

Abstract Continuous wave THz (cw THz) systems define the state-of-the-art in terms of
spectral resolution in THz spectroscopy. Hitherto, acquisition of broadband spectra in a cw …

Frequency-domain terahertz (THz) spectroscopy using photomixing devices has unique
advantages such as high dynamic range and high spectral resolution. Thus, many …

State-of-the-art terahertz time-domain spectrometer can usually only measure one location
point at a time. They require certain working conditions regarding distance and angle to the …

Summary This chapter emphasizes Terahertz (THz) metrology–one of the most problematic
and daunting topics in the THz field, especially the measurement of THz power. Through …

Terahertz time-domain spectroscopy has the potential to revolutionize quality inspection by
allowing contactfree and non-destructive measurements. However, since most currently …

Time-domain spectroscopy (TDS) is the most prominent technique for fast acquisition of
broadband terahertz (THz) spectra with update rates of several ten Hz up to kHz. However …

We present the first comparison of optoelectronic frequency-and time-domain terahertz
(THz) systems for thickness measurements on sub-mm single-and multilayer samples using …
