>> "If you could 3-D print a circuit that manipulates photons instead of electrons, that could pave the way for future applications in light-based computing".

This goes hand in hand with the post that made news on HN 3 days ago about "Researchers demonstrate the first single-photon transistor using a semiconductor"

Where can we learn more about "light-based computing"?

Isn't this similar to how a silicon wafer is made, i.e. pulling an ingot from a melt, except you're now doing things upside down?
