Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
