In the last couple of decades, terahertz (THz) technologies, which lie in the frequency gap
between the infrared and microwaves, have been greatly enhanced and investigated due to …

Within the last two decades, terahertz systems have become a well-established tool in
scientific laboratories and industrial research and development departments. Unlike the …

Continuous wave terahertz spectroscopy based on photomixing offers the attractive feature
of detecting both amplitude and phase of the terahertz radiation. Experimentally, it is …

Terahertz systems can profit from technologies developed originally for telecom
applications. Recent developments on telecom-based key devices are summarized and …

We demonstrate a photonic-integrated circuit for continuous-wave (cw) terahertz (THz)
generation. By comprising two lasers and an optical phase modulator on a single chip, the …

In-fibre wavelength selective modulation of the optical phase enables the electro-optic
control of the terahertz phase in continuous-wave photomixing terahertz systems without any …

We present a terahertz (THz) continuous-wave coherent homodyne spectroscopy and
imaging system based on THz phase control using electrooptic (EO) phase modulation for …

Electro-optical control of the terahertz phase in continuous-wave photomixing terahertz
systems allows the determination of both terahertz amplitude and phase with a single …

The generation and detection of radiation in the THz frequency range can be achieved with
many different electronic and photonic concepts. Among the many different photonic THz …

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 …
