Today’s Spotlight uses an image, courtesy of Chia Wei Hsu, showing a planar slab with a periodic array of holes in which light is found to be confined, although the light is theoretically “allowed” to escape. Blue and red colors indicate surfaces of equal electric field.
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.
