Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. New theoretical results explain how adding a small notch to the disk edge provides a single outlet for laser light to stream out.
