German THz Conference 2015

June 8 - 10, 2015 in Dresden, Germany

HZDR Signet of the Helmholtz-Zentrum Dresden-Rossendorf

Logo DTZ - Deutsches Terahertzzentrum

The German THz Conference will be held in this form for the first time in 2015. Its idea is to bring together German scientists and students working in all fields of THz physics and technology. Held under the auspices of the German THz Center (Deutsches THz Zentrum, DTZ), it is an augmented version of the annual meeting of DTZ, also open to international participation. All talks will be presented in English.

It is planned that in the future the DTZ meeting will be held in this form  – German THz Conference – every second year .

A half-day of this conference (Wednesday, June 10, afternoon) will be devoted to a memorial symposium for Ralph A. Höpfel on the occasion of his 60th birthday. Ralph A. Höpfel  (1955 - 1997), fondly remembered by many in the community, was a pioneer of ultrafast and THz spectroscopy. This is a link to the old homepage of his last group.

It is expected that many of Ralph’s former friends and colleagues will come.

In addition, Jagdeep Shah and Erich Gornik will share their memories of Ralph.


The core scientific program will begin on Monday around 1 p.m. and finish on Wednesday around noon. Wednesday afternoon will be devoted to the Ralph Höpfel memorial session, where all participants are welcome to join.

In addition there will be a industry session with suppliers and users of THz technology.

On Tuesday evening there will be the DTZ Jahresversammlung (for members only) and a conference dinner in Wenzels Prager Bierstuben, a fews steps away from the conference venue. 

The preliminary program can be found here.

The conference will take place at the Dreikönigskirche Dresden in the heart of Dresden.
