One should point out and make clear that Intel's EMIB is electrical only, not optical – contrary to POET's optical interposer, which is both electrical and optical. In Babak Sabi's presentation, the word "optical" occurs in a single place only, and it is closely followed by the word "needed".

The "Bridges Vs. Interposers" articles toots into the same horn: The word "optical" occurs in a single place only, and the corresponding headline is "The challenges".

So, yes, POET Technologies seems to have something very important here. I think we are all curious on when the test results will come and how they will turn out!
