Your question was related to the following statement made by POET 2018.

POET has the tech, it is proven and lots of companies need it!

Your response was that proof would be a successful product qualification.

Yes that would certainly be proof but that is getting the cart ahead of the horse. First you need the technology to be proven which by all the data provided by POET it has. Many of the results reported by Suresh at CIOE demonstrated the superior performance offered by the material properties to all other available technologies in combination with a range of applications that define the optical interposer as a platform technology. Industry experts have warmed up to the benefits that the optical interposer architecture provides because it solves very fundamental problems. And it does it at a really low price using existing equipment.
