It is not really a full silicon platform"
The fact that Intel can appatently fab the laser diodes in silicon on the same die as a chip seems really huge. It was all the way down at the bottom of the article but I think that's the really interesting part.

- greglindahl 10y agoIntel's been making announcements about mastering silicon photonics for a long time - but they've yet to ship anything. I suspect that Omni-Path & associated switches are intended to be an implementation target this time around.
- kchoudhu 10y agoI'm surprised that they haven't cracked the full-silicon problem yet. We were looking at silicon quantum cascade lasers as a replacement for 3/5 QCLs back in college as an undergraduate project way back in 2006, and the lab PI seemed to think that the problem would be solved in two-three years. Unfortunately I had rent to pay, so I had to leave the project and start writing software for a living. I should probably drop my old professor a line and ask her what the happened after I left...
