To bring the sustainable use of light - Green Photonics - in the focus of public attention, and to demonstrate the relevance of light in solving global problems, the innovation cluster Green Photonics of the Fraunhofer-Gesellschaft was launched. In this sense, the Green Photonics Nachwuchspreis is awarded once a year at the fair LASER World of Photonics in Munich.
In particular, with the award young scientists are to be promoted who are working on light, optics, photonics concerning questions of environmental and climate protection as well as conserving resources. The work is assessed on the basis of originality and economic potential as well as the contribution to the objectives of Green Photonics.
This year, a jury of representatives from industry, science and politics decided to award two works from the IAP.
In category B (Dissertations), Martin Steglich was awarded second place for his research on "Black Silicon with ICP-RIE and its applications in optics and opto-electronics".
The master thesis of David Schmelz "Conceptual design and realization of a diffuse light-coupling structure for Ge-on-Si image sensors" was honored twice - with the first place in category A (Bachelor, Master, Diploma) and the special prize of the Foundation for Technology, Innovation and Research Thuringia (STIFT).
The works are based on each; with his research on statistical silicon nanostructures (Black Silicon) Mr. Steglich laid the foundations -amongst other things- for highly efficient silicon solar cells and a Ge-on-Si sensor (Germanium-on-Silicon) for the SWIR spectral range, which was concerned in the thesis of Mr. Schmelz. This new concept is a cost-effective and sustainable alternative as it replaces the much more expensive and environmentally harmful sensors based on indium, mercury and cadmium, and thus also conserving resources. Such novel sensors enable fast and contactless light detection, in particular for the detection of water or moisture. Thus, for example, fruits and vegetables can be tested very easily and quickly for damage points due to their high water content. Other possible applications are in-line methods for level measurements (e.g., drinks) or moisture measurements (e.g., grain / flour). Also, in agriculture and forestry hyperspectral imaging methods can be used in the SWIR for the inspection of fields and forests from air.
Furthermore, SWIR sensors can be used in the recycling industry during sorting of plastics, taking advantage of the different absorption behavior of different plastics.
We also congratulate Astrid Bingel (Fraunhofer IOF) on the first place in category B.
