Progress in the Terahertz region of the spectrum is now such that real engineering applications can be discussed. A large bandwidth is available, unlike X-rays, etc. it is safe for humans and non-destructive. However the radiation is absorbed by water and so not useful for long distance transmission. It may be approached as extending the r.f. spectrum upwards or extending the optical spectrum downwards.
0.3 to 3 THz is also called the submillimetre waveband, and above that is called ‘super THz’. CMOS devices are moving up into the THz range, and applications being found in non-destructive testing and in weapons and security. It is possible to use FET techniques to generate THz frequencies or else two optical frequencies may be mixed in a non-linearity and the THz difference frequency extracted.
About the speaker
Stepan Lucyszyn is Professor of Millimetre-wave Systems and Director of Centre for Terahertz Science and Engineering, Department of Electrical and Electronic EngineeringImperial College London, Exhibition Road
London, SW7 2AZ, United Kingdom
He was awarded an SERC PhD Studentship at University of London (King’s College) in 1989, and after obtaining his doctorate, he worked in industry as a satellite systems engineer for maritime and military communications. He spent 12 years researching microwave and millimetre-wave RFIC/MMICs
Since 2014, has served as a founding member of the Steering Group for EPSRC’s UK Terahertz Network (TeraNet).
He has DSc from Imperial College, and is a Fellow of IEEE. IEE awarded him Fellow status in 2005.
