How to make a CPU – a simple picture-based explanation

Is it possible to embed optic fibers and optoelectronic gates along with semiconductor gates? How is the fabrication process different? Probably there are size limitations due to fiber width and paths?

This is a very active area of research. It's quite technical though so it takes a good amount of study to get into it.

I'm not very familiar with the details, but I know this is an active area of research. Generally you use a process thats conducive to optics (like SOI), you fab the regular silicon in some areas, and you have separate process steps to build the optical devices.
