As we try to fit more and more data on wires, we are running up against the limit of what electricity can do. Wires heat up, and interfere with each other. Fiber-optic cables, using light instead of electricity, have solved many of these problems for long-distance transfer - but inside your computer or your cell phone, the problems persist.
Janelle Shane, alum to the Jacobs School of Engineering at UC San Diego, shows how lasers could provide the next breakthrough for data transfer. But first, how can we shrink a laser to work on the scale of a microchip?
