Thin 3D photonic crystal with diamond-like nanostructure illuminated by white light.
A thin 3D photonic crystal with a diamond-like nanostructure is illuminated by white light from any incident direction (black arrow). Many colors are strongly reflected omnidirectionally irrespective of the incident angle (black arrow). In this example, these are the colors from orange to blue. Image: U Twente.
