Nature: Optical Communication at Record-High Speed

June 8, 2017

Researchers at Karlsruhe Institute of Technology (KIT) and École Polytechnique Fédérale de Lausanne (EPFL) have set a new record for optical data transmission: As reported in Nature, the team exploits optical solitons circulating in silicon nitride microresonators to generate broadband optical frequency combs. Two such superimposed frequency combs enable massive parallel data transmission on 179 wavelength channels at a data rate of more than 50 terabits per second. (DOI: 10.1038/nature22387).

Mit Licht zu maßgeschneiderten High-Tech-Materialien

June 7, 2017

[DE] Kratzer im Autolack per Laser reparieren oder empfindliche elektronische Bauteile mit Licht flexibler oder härter machen: An solchen Lösungen arbeitet Professor Christopher Barner-Kowollik am Karlsruher Institut für Technologie (KIT) und der Queensland University of Technology (QUT) in Brisbane, Australien. Wie sich Beschichtungen und Materialien mit monochromatischem Licht aus Lasern für unterschiedliche Anwendungen maßschneidern lassen, untersucht er nun auch in einem Projekt, das der Australische Forschungsrat mit mehr als drei Millionen Australischen Dollar fördert (mehr als zwei Millionen Euro).

Erasable Ink for 3D Printing

April 24, 2017

3D printing by direct laser writing produces micrometer-sized structures with precisely defined properties. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a method to erase the ink used for 3D printing. In this way, the small structures of up to 100 nm in size can be erased and rewritten repeatedly. One nanometer corresponds to one millionth of a millimeter. This development opens up many new applications of 3D fabrication in biology or materials sciences, for instance.

Solar Cells with Nanostripes

April 12, 2017

Solar cells based on perovskites reach high efficiencies: They convert more than 20 percent of the incident light directly into usable power. On their search for underlying physical mechanisms, researchers of the Karlsruhe Institute of Technology (KIT) have now detected strips of nanostructures with alternating directions of polarization in the perovskite layers. These structures might serve as transport paths for charge carriers. This is reported in the Energy & Environmental Science Journal. (DOI: 10.1039/c7ee00420f)

Optics Advance Quantum Information Processing

April 7, 2017

Experimental physicist Professor Wolfgang Wernsdorfer of Karlsruhe Institute of Technology (KIT) was selected by the European Research Council for funding with an ERC Advanced Grant for his project “Molecular Quantum Opto-Spintronics” (MoQuOS). MoQuOS covers optical manipulation and characterization of molecular quantum bits. Within the framework of MoQuOS, Wernsdorfer, who has been holding an Alexander von Humboldt professorship since 2016, plans to develop together with his team rapid and reliable methods to read out spin states of individual magnetic molecules for quantum information processing.

Reliable Molecular Toggle Switch Developed

March 9, 2017

Nanotechnology constantly allows for new records in miniaturization. Reduction of the dimension of electronic components, however, has physical limits that will be reached soon. Novel materials and components are required. This is where molecular electronics comes in. Scientists of Karlsruhe Institute of Technology (KIT) have now succeeded in developing a molecular toggle switch that does not only remain in the position selected, but can also be flipped as often as desired. This is reported in Nature Communications.

Metal-organic Frameworks Used as Looms

February 15, 2017

Researchers of Karlsruhe Institute of Technology (KIT) have made major progress in the production of two-dimensional polymer-based materials. To produce cloths from monomolecular threads, the scientists used SURMOFs, i.e. surface-mounted metal-organic frameworks, developed by KIT. They inserted four-armed monomers, i.e. smaller molecular building blocks, into some SURMOF layers. Cross-linking of the monomers then resulted in textiles consisting of interwoven polymer threads. This work is now presented in Nature Communications. (DOI: 10.1038/ncomms14442)

Turning Research into Innovations

February 1, 2017

The European Research Council (ERC) has decided to fund two innovative ideas of Karlsruhe Institute of Technology (KIT). For their first steps from fundamental research to commerciali-zation, these projects are now granted about EUR 150,000 each. The so-called “Proof of Concept Grants” serve to further de-velop application-relevant research findings for the market. The KIT projects funded by the ERC cover the analysis of biological samples and data transmission by light.

Background Suppression for Super-resolution Light Microscopy

January 31, 2017

Researchers of Karlsruhe Institute of Technology (KIT) have developed a new fluorescence microscopy method: STEDD (Stimulation Emission Double Depletion) nanoscopy produces images of highest resolution with suppressed background. The new method yields an enhanced image quality, which is advantageous when analyzing three-dimensional, densely arranged subcellular structures. STEDD, a further development of the STED method, is now presented in Nature Photonics. (DOI: 10.1038/NPHOTON.2016.279)

Metamaterial: Mail Armor Inspires Physicists

January 19, 2017

The Middle Ages certainly were far from being science-friendly: Whoever looked for new findings off the beaten track faced the threat of being burned at the stake. Hence, the contribution of this era to technical progress is deemed to be rather small. Scientists of Karlsruhe Institute of Technology (KIT), however, were inspired by medieval mail armor when producing a new metamaterial with novel properties. They succeeded in reversing the Hall coefficient of a material.
