Focus On: Optics & Photonics The latest issue in our Focus On series highlights optics and photonics.  Inside, you'll find an interview with the CPI's healthcare photonics lead and a report on a pan-European effort to develop new optical methods for diagnosing oesophageal cancer. The prospect of using photons instead of electrons to transfer information within data centres holds great promise for faster, more efficient computing, and better techniques for making silicon photonics devices will help accelerate development. Years of painstaking work on new types of blue and green lasers are also starting to pay off, with likely applications in consumer electronics and data storage. And because optics and photonics are "enabling technologies" for a whole range of scientific endeavours, important advances could arise from any one of these areas.

Using light for good Graeme Malcolm, co-founder of M Squared, describes how his company started by making robust, narrow-linewidth lasers for the scientific market and is now branching out into new fields and applications

The promise of silicon photonics Photonics-based computing uses less energy and can transmit data faster than conventional approaches, but the costs of manufacturing silicon integrated circuits with embedded photonic elements have held back progress

Better blue and green lasers A superior class of nitride laser is on the cusp of commercialization thanks to the development of novel mirrors and radical current-injection schemes
