The paper "Nonlinear metal–dielectric nanoantennas for light switching and routing" written by Roman Noskov and colleagues has been noticed in the new issue of Nature Photonics (vol. 6, 2012). A theoretical study has shed light on a hybrid metal–dielectric nanoantenna that allows for dynamic control over its scattering pattern. In particular, the radiation pattern can be reversed by varying the external field intensity, offering potential for ultrafast all optical switching. The system possesses a switching time of just 40 fs.\
