In this interview, https://www.gophotonics.com/interviews/details/interview-with-vivek-rajgarhia-from-poet-technologies, Vivek says volume prod is late 2021 and that was just last month. I don't think there were any unexpected delays (no evidence of that, the supply chain has been constained the same way since early this year), so it could very well be possible that we'll be getting the news we're all waiting for next quarter. GLTA.

Q. What is your product and company roadmap for the next few years?

Vivek Rajgarhia: Through our joint venture with Sanan IC in China, Super Photonics Xiamen, we expect to begin producing our standard products in high volume beginning late in 2021 and early 2022. We have a product roadmap in the data communication segment that includes 100/200 and 400G products. We are communicating with potential strategic partners in all parts of the world to develop photonics solutions in other vertical markets, especially in sensing applications, such as medical devices, wearables, and autonomous vehicles.
