DFG continues funding of the SFB TRR 142 for a second funding period from 2018 to 2021

On November 24th 2017, the Deutsche Forschungsgemeinschaft (DFG) approved the continuation of the SFB TRR 142 for the next four years.

The central scientific goal of the CRC is the exploration and demonstration of a new generation of tailored nonlinear photonics, which is driven by promising concepts from the areas of quantum optics, plasmonics, coherent optics, and ultrafast optoelectronics. This topic is approached by investigating and utilizing different classes of nonlinearities in solid state systems. The TRR 142 concentrate on broad band nonlinear susceptibilities χ(n), resonantly enhanced nonlinearities in excitonic, electronic and plasmonic systems, nonlinear acoustics for the control of light emission, nonlinearities in coherent systems and measurement-induced nonlinearities at the single photon level.

During the first funding period novel nonlinear functional structures were investigated, which are fully integrated quantum optical devices based on ferroelectrics and coherent optoelectronic devices based on semiconductor quantum dots, both for applications in information and optical quantum technologies. Taking advantage of new concepts from, e.g., quantum optics or coherent optics the TRR 142 aims now to develop new applications in the field of quantum technologies.

The long term perspective of the coordinated research program is the design and the active control of nonlinearities, which will be required for new applications in the field of optical technologies, in particular quantum optical devices on a chip, advanced single photon technologies, nonlinear optics with entangled photons, near-field or resonantly enhanced frequency conversion, and coherent functional devices, in particular coherent optoelectronics.

With this concept the CRC will substantially contribute to the future development of nonlinear photonics and emerging quantum technologies, which are based on nonlinearities. The intention is to drive nonlinear optical effects from fundamental research towards new applications, which cannot be realized by linear or classical approaches.
