That's an interesting read, disco68, thank you!

What I find especially remarkable:

• Imec might have managed to grow a III-V epitaxy on a silicon substrate, although the text isn't clear on that. It talks about "integration" of III-V devices with silicon, but I am missing the word "monolithical" here. Not sure whether it was purposely omitted or whether it was an oversight.
• Imec managed to achieve a gain of the indium proportion from 53 to 70% indium. That's very cool! Regarding POET Technologies, "thus far channels of 53% indium have been achieved and the company believes that 80% indium is ultimately possible", we could read in an EE Times article. That was one year (and one day) ago, and they might have further improved on the indium percentage. We don't know. We haven't been given an update since.
• Imec doesn't mention optics, least of all integration of optics and electronics. The optical thyristor remains a very unique asset of POET Technologies, setting the company apart from any competition – Blue Ocean, you know.
• Oh, and Imec is clearly in R&D still. When "results increase the knowledge" and "pave the way", we can deduct that they are still working on the basics. – Good to know POET is already developing a commercial product poised to come out as early as next year!

Ahead of the curve – POET Technologies
