Imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. Researchers now report using an 'air waveguide' to enhance light signals collected from distant sources. These air waveguides could have many applications, including long-range laser communications, detecting pollution in the atmosphere, making high-resolution topographic maps and laser weapons.
