photonic crystals

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.)

Researchers further understanding of wave behaviour in photonic crystals

Newly discovered fundamental rules have been embedded into software to dramatically optimise the design of photonic integrated circuits, Matthew Dale finds
