    Silicon Photonics Chipmaker Xihe Technology Files Registration Version of STAR Market Prospectus

    Shanghai Xihe Technology has released the registration version of its STAR Market IPO prospectus, describing itself as one of the world's major suppliers of silicon photonic integrated chips. Its customers include leading optical module makers and cloud service providers, and its products are already shipping at scale into AI clusters and hyperscale data centers. According to estimates by optical module makers, at the same speed and distance, silicon photonic solutions can reduce total cost by nearly 20% and cut the volume of components within a module by nearly 30%.

    Why we recommend it: The source provides cost and volume data for silicon photonics versus discrete components, helping to understand the domestic supply chain for AI data center optical interconnects.
