In a new paper with Kostas, Ivor and Andre, we demonstrate how a dielectric medium can be made invisible for certain incoming beams when a suitable spatial distribution of gain and loss is added to the medium’s permittivity.
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.
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.
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.
