If "it is unlawful to traffic in tools that allow fair use circumvention", why haven't they closed down all the VCR manufacturers? Is VHS encoding not a type of encryption?
Electron migration is only a problem because it knocks (migrates) metal atoms out of a section of wire when you have high current densities. Basically it leads to an break in the connection. Light can travel through 'empty' space. If it one photon knocks something out of the way the next one can still come through.
The thing is you can't use the same manufacturing processes to create a photonic chip. Plain/doped silicon (that intel and AMD use) isn't a practical way to deal with light. Eventually the processing for something like this could get to the point where it is as inexpensive but only after Billions of dollars of investment in processing techniques. And then the fabrication facilities will still cost billions.
This kind of thing has great potential but nothing that is going to happen overnight, or even in a year or two. Probably not in the next 3 years, not unless Intel/IBM/ (your choice of multi-Billion dollar corporation) invests majorly in it.
