Wireless sub-THz communication system with high data rate enabled by RF photonics and active MMIC technology
S. Koenig,D. Lopez-Diaz,J. Antes,F. Boes,R. Henneberger,Arnulf Leuther,Axel Tessmann,Rene Schmogrow,David Hillerkuss,Robert Palmer,Thomas Zwick,Christian Koos,Wolfgang Freude,Oliver Ambacher,Juerg Leuthold,Ingmar Kallfass +15 more
TL;DR: In this paper, a single-input and single-output (SISO) wireless communication system with a carrier frequency of 237.5 GHz is presented. But the system is not suitable for large-scale data transmission.
Journal ArticleDOI
All Active MMIC-Based Wireless Communication at 220 GHz
Ingmar Kallfass,J. Antes,Thomas Schneider,F. Kurz,D. Lopez-Diaz,Sebastian Diebold,Hermann Massler,Arnulf Leuther,Axel Tessmann +8 more
TL;DR: The paper presents system considerations for wireless links in the 200-300-GHz range, discusses the design and performance of dedicated broadband transmit and receive MMICs, and presents link experiments.
Journal ArticleDOI
THz-to-optical conversion in wireless communications using an ultra-broadband plasmonic modulator
S. Ummethala,T. Harter,K. Koehnle,Zheng Li,S. Muehlbrandt,Yasar Kutuvantavida,Juned N. Kemal,Pablo Marin-Palomo,J. Schaefer,Axel Tessmann,Suresh Kumar Garlapati,Andreas Bacher,Lothar Hahn,Markus Walther,Thomas Zwick,Sebastian Randel,Wolfgang Freude,Christian Koos +17 more
TL;DR: This work reports on the first demonstration of a THz link that is seamlessly integrated into a fiber-optic network using direct terahertz-to-optical (T/O) conversion at the wireless receiver.
Journal ArticleDOI
64 Gbit/s Transmission over 850 m Fixed Wireless Link at 240 GHz Carrier Frequency
Ingmar Kallfass,F. Boes,T. Messinger,J. Antes,Anns Inam,U. J. Lewark,Axel Tessmann,R. Henneberger +7 more
TL;DR: A directive fixed wireless link operating at a center frequency of 240 GHz achieves a data rate of 64 Gbit/s over a transmission distance of 850 m using QPSK and 8PSK modulation, in a single-channel approach without the use of spatial diversity concepts.
