2nd Green Photonics Symposium

TU Berlin and Technion Haifa jointly organize and support a two day symposium - funded by the Reinhard Frank Foundation - at TU Berlin on March 30th and 31st, 2015, focusing on key technologies of the 21st century based on the advanced use of photons, a contribution to the UN year of light 2015.

The symposium will address the most pressing issues facing the computer and telecommunication industries as well as research communities:

The large energy consumption associated with the ever increasing internet use and the lack of efficient renewable energy sources to support it.

Energy harvesting based on latest achievements in photovoltaics, energy efficient data communication and computing together with similar urgent topics addressing challenges of our future green society will be addressed by leading researchers and developers from industrial and government laboratories worldwide.

  • Energy Problems in data-com systems
  • Energy problems in computers: from systems to the chip level
  • Advanced solar energy harvesting

Within the celebrations of the 50th anniversary of diplomatic relations between Israel and Germany.

As a political prelude on the morning of March 30th 50 years of diplomatic relations between Israel and the Federal Republic of Germany will be honored by key government members of both countries. At the same time 100 years of closest ties between Technion and TUB (the former TH Charlottenburg) will be remembered and praised.

The symposium will finally present an outlook on the efforts of both leading Technical Universities on developing jointly novel technologies and applications serving our societies in the 21st century. Cooperation of young researchers will be fostered and financially supported in the frame of the network.

Venue + Accomodation

The Green Photonics Symposium takes place in the physics building of the Technische Universität Berlin.

Lecture Hall EW 201 (2nd floor),
Eugene-Paul-Wigner building

Technische Universität Berlin
Hardenbergstrasse 36
10623 Berlin, Germany


Eugen-Paul-Wigner Building

Many hotels of any category are in walking distance to the Technische Universät Berlin. On the basis of our good experience in the last years we can suggest the following Hotels (for invited speakers the Hotel is already booked by the organizers!):


By Plane - Airport Berlin Tegel (TXL)

The airport is very close to the Main Campus. Take the airport shuttle bus (X9) to Ernst-Reuter Platz (15 minutes) or take a taxi (ca. 10 minutes, ca. 20 €).

By Plane - Airport Berlin-Schönefeld (SFX)

This is across the city, so a taxi is expensive unless you can share the costs (ca. 45 minutes, ca. 40 €).

At S-Bahnhof Flughafen Schönefeld take a regional train (RE7, destination Dessau) or S-Bahn (Line 9, destination Pankow, change at Ostkreuz to any train in direction of Zoologischer Garten). Leave the train at Zoologischer Garten. From there you can walk down Hardenbergstrasse (five minutes), take a bus (M45, 245, or X9) or you can stop a taxi and take a fixed rate short ride.

By Rail - Station Berlin-Hauptbahnhof

At Central station take a regional train or S-Bahn (any line in direction of Charlottenburg, Westkreuz, Potsdam or Spandau) to Zoologischer Garten. From there you can walk down Hardenbergstrasse (five minutes), take a bus (M45, 245, or X9) or you can stop a taxi and take a fixed rate short ride.
