The entire internet backbone is fiber optic cables, so most data is already transferred using "beams" of light.
This is what computers do on either end of the fiber optic cables to transmit the data; except billions of times faster, using multiple "colors" (wavelengths) and similar tricks with light to stream as many 1's & 0's as fast as possible.
