Azimuthal emission pattern of a photonics crystal LED. The scattering of the few guided modes of the LED's thin vertical layer stack by the photonic crystal results in a Star‐of‐David‐shaped pattern for a single frequency. The scanning electron microscope picture in the background shows the hexagonal lattice. (Picture: C. Wiesmann et al., pp. 262–286, in this issue)
