The perfect trap for light

Together with the team of Ori Katz at the Hebrew University of Jerusalem we just published a paper in Science on how to trick light into getting perfectly absorbed even in a weakly absorbing layer. The idea is to put a degenerate cavity around the absorber, which uses interference to prevent any light from escaping this absorbing trap of light. The article has been highlighted in a very elegant Perspective article written by Jacopo Bertolotti, as well as in Physics World, in the New Scientist and in the APS Physics Magazine. From our team, Helmut Hörner was in charge of simulating the complex interference in this device. Thanks to all for the excellent collaboration!
