In a new paper with the group of Yun-Feng Xiao published today in Nature Communications we show how the non-linearity in a symmetric microcavity leads to the formation of lasing modes with a pronounced chirality that we can control dynamically and all-optically by the bias in the pump direction.
Our group is now part of the Erwin Schrödinger Center for Quantum Science & Technology (ESQ), which is an Austria-wide postdoc and discovery programme dedicated to highly innovative research. Funding comes from the Austrian Federal Ministry of Education, Science and Research (BMBWF) and the coordination is carried out by the Austrian Academy of Sciences (ÖAW).
A new paper with our collaborators in Nice and London just appeared in Nature Photonics and is highlighted in OSA Optics & Photonics News and in Pro-Physik. In this work we demonstrate how to design the optimal wave front to deliver the highest possible force or torque onto a target embedded in a complex environment (see illustration on the left for a wave field transferring a strong torque onto a square target).
A joint work with Hasan Yılmaz and the group of Hui Cao just appeared in Physical Review Letters. We show that high-transmission channels in disordered media have an increased range of the angular memory-effect.
