An Illustration of the Light Box (IMAGE) Chalmers University of Technology Caption Using a box built from stacked atomically thin layers of the material tungsten disulphide (see the atomic model), Chalmers researchers have succeeded in creating a type of feedback loop in which light and matter become one. This new concept involves two distinct processes being housed in the same nanodisk. The box has a diameter of only 100 nanometres (0.00001 centimetres) and opens the way to new fundamental research and more compact solutions in nanophotonics.
