Initiation of a new journalclub at the CRC/TRR 142
PhD students of the TRR142 recently initiated a new journal club (organized by PhDs for PhDs).
They meet regularly during terms to discuss up-to-date papers of their field of interest.
The papers will be presented by one of the PhDs and discussed by the participants in a relaxed atmosphere and in the absence of their supervisors.
The aim of this journal club is, on the one hand, to broaden…
When natural occurring nonlinear material is excited by strong laser light the different propagation velocities of light for the different wavelengths result due to destructive interference in a weak signal. In the novel tailored nonlinear material the second harmonic generation is induced in specific structures at nanoscopic scale with a well-defined phase. To obtain such additional phase by each artificial atom the concept of spin rotation coupling of light is used to control the phase of the structure of the material which finally results in a constructive interference and an enhancement of the signal.

TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen
Prof. Dr. Thomas Zentgraf and his team (University of Paderborn) has developed in collaboration with researchers from the University of Birmingham a new method to tailor the nonlinear optical properties of artificially structured material. With their new approach completely novel properties of materials can be obtained which cannot be implemented by naturally occurring materials.
Physicists from the TRR 142 and CeOPP organize this year the German MBE-workshop.
The meeting takes place on September 21st/22nd 2015 at the University of Paderborn.
The aim of this meeting will be exchanging scientific knowledge and experience as well as addressing technical problems and challenges with respect to molecular beam epitaxy. Thus, the scientific program and the industrial exhibition will complement one another.
The UNESCO has declared the year 2015 as the “International Year of Light 2015”. Several international events are coordinated by the UNESCO and their partners as well as the European Physical Society. In Germany several activities are coordinated by the German Society of Physics (DPG).
Investigating in the many aspects of the science of light is the main focus of the Physicists of the TRR 142.
Delivering insight to the public the group of…
