Welcome to the Institute of Photonics and Quantum Electronics (IPQ)

The IPQ and the Institute for Microstructure Technology (IMT, Campus North) have merged. The merger will reinforce the research activities in the field of micro- and nanotechnologies.



Koos Landesforschungspreis
State Research Award (Landesforschungspreis) 2014 goes to Christian Koos

October, 2014: Prof. Dr. Christian Koos received State Research Award (Landesforschungspreis) 2014 for applied research. In their joint experiment, the researchers of IPQ and the EPFL (Ecole Polytechnique Federale de Lausanne) have demonstrated that integrated optical frequency comb sources with large line spacings can be realized on photonic chips and applied for the transmission of large data volumes. They reached a data rate of 1.44 terabits per second: This corresponds to a data volume of more than 100 million telephone calls.

Looking back on the 115th Annual Meeting of the DGaO

The Institute of Photonics and Quantum Electronics looks back on the successful 115th Annual Meeting of the German Society for Applied Optics (DGaO). More than 260 representatives of industry, scientists and students attended the event at the Concert House (Konzerthaus) in Karlsruhe. The meeting provided an excellent opportunity to discuss a wide range of topics and to share ideas with colleagues and exhibitors. 

Nature Photonics: Terabit communications with miniaturized optical frequency comb source

April 14, 2014. Publishing in the well-known journal Nature Photonics we present our recent results obtained with microresonator-based frequency combs. For the first time we show that these so-called Kerr combs can be used for coherent data transmission systems and enable data rates of more than a terabit/s. Such sources could be used for example for chip-scale terabit/s optical interconnects.
