Electro Optics coverPhotonc sensor to combat TB

A lab-on-chip device, being designed as part of a European project, promises to reduce the cost of diagnosis tuberculosis dramatically – and save many lives in the developing world. Greg Blackman speaks to Wim Van Roy at Imec, one of the coordinators of the project

Electro Optics coverKeeping count on light

Highly sensitive detectors are enabling techniques like quantum cryptography and forms of flourescence spectroscopy. Tom Eddershaw investigates the technology for detecting individual photons

Electro Optics coverSolar research leads to laser discovery

Perovskites are being tipped as materials that will revolutionise solar power. Now, an Oxbridge team of scientists have used its luminescent properties to make a laser from the mineral. Greg Blackman speaks to Dr Felix Deschler and Michael Price of Cambridge's Cavendish Laboratory, who worked on the project

Electro Optics coverLasers in profile

Greg Blackman gets to grips with the various methods for analysing high-power lasers, including a novel method that calculates power according to the weight of the beam
