New Pub­lic­a­tions | Po­lar­isa­tion and to­po­lo­gic­al ef­fects in coupled op­tic­al sys­tems

Three research groups at the Institute for Photonic Quantum Systems and the Physics Departement of Paderborn University  – Theory of Functional Photonic Structures (Prof. Dr Stefan Schumacher), Ultrafast Nanophotonics (Prof. Dr Thomas Zentgraf) and Theoretical Quantum Science (Prof. Dr Jan Sperling) – have made progress in the field of modern photonics in their latest work. In two publications, the researchers investigated how light can be…

Re­cog­nising heavy metals in soil and wa­ter: New meth­od for on-site ana­lys­is

As part of an international team, scientists from Paderborn University have developed a new method to quickly and accurately detect toxic arsenic variants in soil and water. The study, which was published in the journal "Nanoscale" of the Royal Society of Chemistry, shows how simple technologies can replace expensive laboratory procedures and enable rapid on-site analysis.

Our fire drill

Safety always comes first and fires cannot be ruled out even in our laboratories. So we took advantage of the nice weather and conducted a fire safety drill again after a long time. This includes not only knowing how to behave in an emergency, but also how to use the fire extinguishers. Many thanks to Mr. Hohrath from Department 5 for the professional instruction.

Metas­ur­faces en­able mini­atur­ized op­tic­al pulse shaper

Material dispersion accumulated in optical setups tends to heavily distort and chirp ultra-short laser pulses which can be especially disadvantageous in nonlinear optical applications or pump-probe experiments. In our recent publication ‘Compact metasurface-based optical pulse-shaping device’ published in Nano Letters, we show that multiple metasurfaces on a single glass substrate can be used, to alter the dispersion of ultra-short laser pulses…
