Triple career success

General

This year, three of our present and past postdocs in the group have obtained faculty positions in India as well as research positions in Croatia and at the CNRS in France. Congratulations to Himadri, Ivor and Nicolas!

The indestructible light beam

Scientific publication

Together with the team of Allard Mosk at Utrecht University, we published a paper in Nature Photonics in which we introduce the concept of “scattering-invariant modes”. These special light waves have the property that they produce the same light pattern in the far-field, irrespective of whether a strongly scattering medium is put in their way or not (see image on the left). Find out more about these indestructible beams of light in the news highlight on Physics World or in the freely available version of the article.

Lise Meitner

Lise Meitner fellowship for Ivor

Grants

Ivor Krešić was awarded a Lise-Meitner fellowship by the Austrian Science Fund (FWF), which will allow him to continue his successful work as a postdoc in our group. Ivor will primarily work on waves in non-Hermitian media and shall collaborate with our experimental partners on the implementation of his theoretical predictions.

Target behind a disordered medium

Optimal information about the invisible

Scientific publication

Together with Dorian Bouchet and Allard Mosk from the Nanophotonics group at Utrecht University, we demonstrated how to shape the wave-front of a coherent laser beam such as to obtain with it the maximal possible information about a target hidden behind or inside a disordered medium. Our joint work was published in Nature Physics and is described in the following press release compiled by Florian Aigner from the press office at TU Wien (see also highlight in Physics World).

Adaptive control of quantum cascade random lasers

Scientific publication

Together with the THz lab at TU Wien we show in a new Nature Communication that quantum cascade random lasers can be adaptively controlled by a suitably shaped infrared beam. Following a control strategy developed by Nicolas Bachelard, an initially multi-mode THz random laser is turned into a tunable single-mode source. Discussions of our work can be found at the Austrian Press Agency, Chemie.de and at Analytica News.
