NDT Applications of All-electronic 3D Terahertz Imaging
Terahertz imaging offers interesting opportunities for industrial non destructive testing (NDT). Components made e.g. of fibre-reinforced plastics and ceramics can be inspected very efficiently. 3D Terahertz offers several advantages over established methods like ultrasound, active thermography and X-ray. This presentation gives an overview of the basics and presents results of detailed application work.

InP Transistor Technologies for Terahertz Monolithic Integrated Circuits (TMICs)
Ultra-high speed Indium Phosphide (InP)-based transistor technologies are enabling new classes of THz frequency integrated circuits. In this presentation, we will describe an InP heterojunction bipolar transistor (HBT) technology that has demonstrated complex integrated circuits operating up to 670GHz. Technology considerations ranging from transistor and IC design to TMIC packaging and test will be presented.

Cascade Microtech
Enabling accurate on-wafer device characterization in the mmw/THz range
On-wafer device characterization at THz frequencies are calling new approaches for accurate calibrations and measurement results. This includes optimized probe system designs and wafer probes. For calibrations identical probe launch for calibration standards and device under test is important to consider technology parameters. Probe placement accuracy on smaller structures gets more critical.
This presentation shows Cascades ideas and solutions to enable accurate THz On-wafer measurements and how to deal with these challenges.

SWISSto12 SA
Guided THz Transmission enabling applications
Regardless of the scope, a functional THz application requires three main elements: the source capable of generating the THz signal of interest, the signal transmission line and the final target. One of the missing elements that predominantly prevent a widespread implementation of applications over the full THz frequency range are efficient and commercially available THz signal transmission components. Thanks to its unique technology, SWISSto12 supplies waveguides and antennas for high-performance THz signal transmission.

THz technology for meteorological and space applications
Microwave, millimeter and sub-millimeter wave semi-conductor based technology is increasingly used in ground-based, airborne and space-borne active and passive radiometers in order to retrieve key atmospheric data, which is in turn fed into advanced Earth weather forecasting and planetary atmospheric circulation models. We will present the latest THz technology developments at component, sub-system and system levels to support these applications.

Terahertz Materials Characterization in extreme environments
Terahertz (THz) waves span the region of the electromagnetic spectrum between millimeter waves and the far-infrared (IR) and have energies which are comparable with carrier scattering in semiconductors, low frequency crystalline lattice vibrations in molecular solids, and magnetic resonances in novel spin materials. At this energy scale, a broad range of materials from biomolecules to semiconductors can be characterized with terahertz frequency spectroscopy, and the addition of cryogenic temperatures and large magnetic fields to conventional THz spectroscopies can uncover details of novel phenomena in materials such as superconductivity, structural and spin-order phase transitions, and electron-phonon coupling. We report on the development and applications of a turnkey platform for continuous-wave THz interrogation of materials in a cryogenic temperature, high magnetic field environment.

Recent Progress In Commercial Cryogenic THz Detector Technology
The promotion of THz techniques beyond the controlled environment of a research laboratory into the civil theatre requires robust, reliable, convenient high performance devices such as sources and detectors. Detector performance is limited by fundamental physics according to its operating temperature, and as a consequence there is a huge advantage in developing cryogenic systems that are easy to use. I describe our recent work to develop high performance THz sensing in single detector and array formats without the need to handle or consume liquid cryogens.

BrightSpec
Trace Detection of Volatiles using Fourier Transform Molecular Rotational Resonance Spectroscopy
The quantized rotational motion of molecules in the gas phase produces a high-resolution spectrum with exceptionally high chemical selectivity. At room-temperature, the intensity of the rotational spectrum peaks in the 200-1000 GHz frequency range. Advances in high-power, solid state terahertz (THz) sources have enabled the development of Fourier transform measurements of the molecular rotational resonances. Fourier transform techniques have achieved a 10,000‑fold reduction in measurement time compared to traditional absorption spectroscopy techniques. Molecule detection levels in the 100 fmol – 10 pmol range are obtained for measurement times on the order of 10 minutes for a wide range of molecules. The BrightSpec implementation of chirped pulse Fourier transform molecular rotational resonance (FT-MRR) spectroscopy will be presented. A key feature of FT-MRR spectrometers is their high spectral resolution that permits direct analysis of complex gas mixtures without the need for chemical separation by methods like gas chromatography. Examples of gas mixture analysis is simple gas samples and from headspace sampling will be presented. Unique analysis techniques of FT-MRR spectroscopy will be described. These include the ability to perform site-specific isotope analysis, determine the mass of an unknown molecule, and determine the absolute stereochemistry of a chiral molecule.
