optic fibre cables . Optic sound cables. We can use light to transmit data. I am sure we can use light to project data , and lasers to do all sorts of things. As for Paul Davies idea that there is some inherent organising information in light and gravity I think that is not really a science question.

As to whether we can modulate individual photons and transmit information like we do with Radio / TV or microwave communications I don't know.
