Janelle Shane, an alumna of the Jacobs School of Engineering at UC San Diego, and specialist in photonics has a prescription for increased Internet speeds: tiny lasers.
The switch from electrical wires to fiber-optic cables has already begun improving Internet speeds around the world.
"We can fit a lot more information on one strand of glass than we ever could on a wire, because we can put different colors of light down the same wire," said Shane.
But the problems with electrical wires -- namely heat and interference –- remain inside our devices.
"We want to try and use those same advantages that we got from fiber optics on a computer chip, for sending data not only between computers but now within computers as well," said Shane.
The challenge: making lasers small enough to fit on microchip.
