Photonic integrated circuits (PICs)

When connected to a laser beam, the new thin-film circuit produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics, imaging and telecommunications. (Image: EPFL)

Integrated photonic circuits could help close the 'terahertz gap'

The chips show promise for a whole host of applications in optics, spectroscopy, imaging and telecommunications

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
