Invited Seminar: Applications of terahertz technology – from research to industry
Photonex 04, Stoneleigh, Coventry, UK, 7th October: 1pm. HT Consultants Ltd
The terahertz (THz) gap represents the final frontier of the electromagnetic spectrum.
Typically defined in the frequency range 0.1 THz to 10 THz, (1 THz = 1012 Hz, 33 cm-1 or 300 microns)
the terahertz region lies between the infrared and microwave regions of the electromagnetic spectrum.
Over the last thirty years terahertz technology has been applied to astronomy and atmospheric sensing
to investigate the origins of our universe and atmospheric constituents. Solids, liquids and gases
display distinct signatures in the terahertz region, which arise from molecular rotation, twisting and
torsional modes and hydrogen bonding. These unique spectral signatures can provide additional or complementary
information to other spectral techniques and thus terahertz technology is of particular scientific interest.
Following the development of pulsed coherent sources and detectors in the eighties and early nineties, the role
of terahertz technology for terrestrial imaging and spectroscopy applications has been investigated in earnest.
Potential applications range from the medical industry with the imaging of skin cancer, to the identification of
toxic substances in security. The search for the so called ‘killer application’ is still ongoing. This recent surge
in activity in the field has lead to an increased profile of the technology, funding and demand for innovation.
This seminar provides a historical overview of terahertz technology and discusses the current applications and
potential of this newly emerging field from research to industry.
