It was predicted in recent years that a non-chiral particle in an evanescent optical field (such as one generated by total internal reflection) is able to acquire linear momentum perpendicular to the plane of incidence from the spin component of the incoming light. When the helicity of the light is flipped, this momentum changes direction. […]
Opinion piece in Belgian newspaper De Morgen. Science is a story of many punctuation marks. The facts (!) the context (,) the nuance (;) but also the questions (?). In this article, we highlight about the importance of those question marks. Full article can be read here.
Ultrathin nanostructured resonators on surfaces, i.e., metasurfaces, have shown great potential for the miniaturization of advanced photonic technologies such as aberration-free lenses, beam shapers, and holograms. These metasurface designs focus strongly on obtaining desired optical properties through a careful optimization of the shape, the relative orientation, and the composition of structures. However, once manufactured the […]
