Abstract:
The number of worldwide research activities focusing on the interaction
of terahertz (THz) radiation with various forms of matter is growing
very rapidly. Highly attractive THz applications emerged in the fields
of non-invasive biological and medical diagnostics, chemical sensing,
non-destructive material testing, security applications and high-speed
telecommunications. Still in an early stage, the current research in
solid-state THz technology is mainly directed to individual component
development with focus on the improvement of specific properties like
detector sensitivity, source power, and device operating temperature. In
order to promote the transfer of terahertz technology from lab to real
world applications a mature technology platform (like Silicon) for
cost-efficient compact device is urgently needed. Silicon nanophotonic
structures bear a great but still largely underutilized potential for
optical THz signal generation and detection. In this presentation some
basic concepts are discussed and first proof-of-principle experiments
will be presented.
Biography:
Michael Nagel was born in Viersen, Germany, in 1970. He received his
Ph. D. from the Rheinisch-Westfälische Technische Hochschule (RWTH)
Aachen University, Germany, in 2003. During his thesis, he developed
the world-wide first label-free DNA sensor chip utilizing THz range
frequencies. Since 2004 he is chief engineer at the Institute of
Semiconductor Electronics, RWTH Aachen, where he directs applied and
fundamental research projects focusing on terahertz technology.
He has authored or co-authored over 80 publications and international
conference presentations and filed six patents. Dr. Nagel was awarded
with the Roberts Prize 2004 of the Institute of Physics and Engineering
in Medicine and is recipient of the Wilhelm Borchers Medallion of the
RWTH Aachen University.
