Nvidia has decided to temporarily give up using TSMC’s COUPE technology.

Golden Finance reports that, according to sources, Nvidia has decided to temporarily abandon adopting TSMC’s COUPE (compact general-purpose photonic engine) technology, because TSMC’s progress in advancing silicon nitride (SiN) technology has been slow and the development of the two-dimensional grating coupler has not met expectations.
Nvidia’s earlier “Plan A” approach was based on the TSMC COUPE co-packaged optics platform, while the latest “Plan B” has shifted to Tower Semiconductor’s silicon photonics platform.
