Scaling challenges of metasurfaces

Greg Blackman explores the optical design approaches for modelling metasurfaces

Crucial point-of-care comes closer

Delivering diagnostics at the time of testing improves healthcare outcomes, but requires photonics firms who develop optical sensing technologies such as spectroscopy, to adapt to the changing needs of the medical sector

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
