Variety of applications abound with new way to trap light [Registered]

The ability to confine light is important both scientifically and technologically. Many light confinement methods exist, but they all achieve confinement with materials or systems that forbid outgoing waves. There are several ways to “trap” a beam of light – usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that could find a wide variety of applications. The new system, devised through computer modelling and then demonstrated experimentally, pits light waves against light waves: It sets up two waves that have the same…
