Physics World Focus on: Optics and photonics
Exploring the power of light
This special focus issue of Physics World explores some of the latest research in optics and photonics. Our cover feature surveys the latest advances in invisibility cloaking – 10 years after first being demonstrated at microwave frequencies. We look at the optical systems underpinning NASA’s recently approved dark-energy mission WFIRST, explore a 5D optical memory that promises eternal data storage, and report on a new route to quantum computing based on optical frequency combs. We also catch up with two state-of-the-art laser centres nearing completion in Europe: CALA and the Extreme Light Infrastructure.
