At the last Toronto AGM lunch in which many shareholders attended I had the opportunity to speak with Suresh on a few topics (not all technical). As Senior VP Technology Development at Global Foundries he had access to very big funding . Their R&D budget for 2022 was $482 million USD. 

Can you imagine where POET would be today if they had access to big money. The kind of funding that comes available from partnerships and collaborations with leading companies within the industry. Just a matter of time as there is very big interest in the approach that POET has taken with some emulating it on an inferior Silicon Photonics platform.
