MINT-toolbox to control the emission of photons (with record inhibition :-)
Recently, a team of chemists, mathematicians, physicists and nano-engineers at the University of Twente in the Netherlands developed the ultimate device to control the emission of photons with unprecedented precision. This technology could lead to more efficient miniature light sources, sensitive sensors, and stable quantum bits for quantum computing. The part of your smartphone that […]

Nanophotonics at home: “why are dust flakes grey?” (COPS in NRC news)
Recently, the science section of leading Dutch newspaper NRC ran a story – in response to reader questions – on “why are dust flakes grey?” (click sorry if there’s a paywall). The question notably addresses dust as flakes”, in Norway also known as “hybelkaniner” (~student dorm rabbits :-))  and in Britain as “dust bunnies”. In […]

Curves ahead: controlling light through free-form industrial optics
When light travels from A to B through a transparent material, it takes a path whose prescription has been well-known ever since Pierre de Fermat’s 1658 work, even when the material has arbitrary shape, so-called free-forms. A major challenge arises when the material is not only freeform but also opaque, like white light-emitting diodes (LED): […]
