Lasers and sensors offer bird’s eye view on climate change

In orbit, in the air or even on the ground, photonics technologies give us a precise big picture on climate change, discovers Ben Skuse

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

A picture perfect free-space broadcast

Designers, builders and operators of free-space networks can leverage LWIR quantum cascade lasers (QCLs) to achieve multi Gb/s data transfer rates. Find out how
