(Phys.org) —The optical fiber network that spans the globe consists of millions of miles of fibers that bring us our Internet, cable TV, and telephone services. Now researchers have shown that this global network offers ...
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 ...
