Best Student Paper Competition at ECOC2019:

September 2019: Tobias Harter and Christoph Füllner, PhD candidates at the IPQ, won the Runner Up Prize in the BestStudent Paper Competition during the European Conference on Optical Communication (ECOC2019) for their paper "Generalized Kramers-Kronig Receiver for 16QAM Wireless THz Transmission at 110 Gbit/s". Their work demonstrates a greatly simplified coherent THz receiver, which can be used for high-speed wireless communications.

Optica: Terahertz optoelectronics for future wireless networks

August 2019: Scientists at IPQ/IMT in collaboration with Fraunhofer institutes have shown a wireless THz transmission link that exploits optoelectronic processing both for signal generation at the transmitter and for coherent detection at the receiver. Using a high-speed photoconductor and a photonic local oscillator for optoelectronic down-conversion, the team has demonstrated wireless transmission at up to 30 Gbit/s over more than 50 m as well as wideband tunability of the carrier frequency between 0.03 THz and 0.34 THz. The paper appeared in the current issue of Optica.

Preisträger Innovationspreis
IPQ/IMT team receives Second Prize at the competition for the Berthold-Leibinger Innovation Prize

July 2018: The IPQ/IMT project team "DELPHI - 3D Laser Lithography for Photonic Integration" will receive the Second Prize of the renowned Berthold-Leibinger Innovation Prize. The DELPHI project group, headed by Christian Koos, was dedicated to industrial adoption of femtosecond laser lithography as a tool for 3D additive nanofabrication in integrated photonics and has led to foundation of the start-up company Vanguard Photonics GmbH. The project builds upon multi-photon lithography for fabrication of single-mode photonic waveguides and free-form micro-optical elements for efficient coupling of optical microchips. The award ceremony will take place on September 21, 2018 in Ditzingen, Germany.
