Wireless THz link with optoelectronic transmitter and receiver
T. Harter,S. Ummethala,Matthias Blaicher,S. Muehlbrandt,Stefan Wolf,M. Weber,Mosaddek Hossain Adib,Juned N. Kemal,Marco Merboldt,F. Boes,Simon Nellen,Axel Tessmann,Martin Walther,Björn Globisch,Thomas Zwick,Wolfgang Freude,Sebastian Randel,Christian Koos +17 more
TL;DR: This paper shows that wireless THz receivers can also greatly benefit from optoelectronic signal processing techniques, in particular when carrier frequencies beyond 0.1 THz and wideband tunability over more than an octave is required.

InAs/GaSb superlattice focal plane arrays for high-resolution thermal imaging
Robert Rehm,Martin Walther,Johannes Schmitz,Joachim Fleißner,Frank Fuchs,Johann Ziegler,Wolfgang A. Cabanski +6 more
TL;DR: In this article, the first fully operational mid-IR (3-5 μm) 256×256 IR-FPA camera system based on a type-II InAs/GaSb short-period superlattice showing an excellent noise equivalent temperature difference below 10 mK and a very uniform performance has been realized.
