I think there is a good chance that there is a new JV in the works which will provide some momentum. Recall Luxshare reference to POET: https://www.prnewswire.com/news-releases/luxshare-tech-preview-for-ofc-2024-collaborating-with-ecosystem-partners-to-explore-cutting-edge-technologies-302087509.html

POET is a frontrunner in Photonic Integrated Circuits (PIC) technology, with products widely used in optical communications, LiDAR, and other applications. By partnering with POET, Luxshare-TECH accelerates progress in PIC technology research and application, propelling the optical communications industry towards higher integration and lower power consumption.

The mention of LiDAR makes me think there is something in the works on this front as well.

 They need to be in a position to capitalize on any event that will light the fuse.
