Light sculpts three-dimensional crystals in nonlinear optical materials

Scientists from the University of Muenster and the Indian Institute of Technology have experimentally demonstrated for the first time the creation of 3D photonic crystals and quasicrystals with a plethora of geometries and forms purely by the action of light in a nonlinear optical material, which allows reconfigurable as well as scalable crystal and quasicrystal formation.
