This is from the latest POET-Blog entry :

Celestial AI: POET Starlight™ is a lightbar component in Celestial AI’s flagship product, Photonic Fabric, that is designed to shatter the memory wall and deliver data directly to the point of compute. An 8-channel packaged light source for chip-to-chip AI applications and co-packaged optics for the data center market, Starlight can be integrated on a host board and connected to chips and ASICs with built-in silicon photonics. POET will supply initial production orders to Celestial AI in the second half of 2024.

It is fitting together with this CAI - interview from June 24 :

==> IMO the most important sentence from this interview for POET is :
"We are working with the major OSATs on the interposer. We are in the process of scaling up capacity. We will consume a huge percentage of silicon photonics capacity in 2025 and 2026.”
