I think we had some personnel connections between other known connections that were explored some time ago. So, it being a lazy Sunday, I asked ChatGPT the title question. It cited our forum and POET's website, which made me chuckle. I think POET was getting lasers from Broadcom. 

As of now, there is no specific information indicating that POET Technologies is actively working with Broadcom. However, POET Technologies is involved in significant partnerships with other major companies in the technology and AI sectors. For example, POET has established collaborations with Foxconn Interconnect Technology and Luxshare Technology, focusing on developing advanced optical engines and transceiver modules for AI and data center applications.

POET's collaborations are aimed at integrating their photonic technology into high-speed data solutions, which are critical for the growing demands of AI networks. These partnerships with key players in the industry suggest that POET is positioning itself as a major contributor to AI and photonics technology, though Broadcom has not been specifically mentioned in their recent public disclosures​
