Advantest and OpenLight join forces on silicon photonics test platform for mass production

Advantest’s collaboration with OpenLight on a scalable silicon photonics test platform signals a pivotal shift from R&D to wafer-scale manufacturing in optical interconnects. This move pressures upstream laser integration (e.g., InP hybrid bonding) toward standardization and compels OSATs to overhaul ATE architectures for concurrent electro-optical validation. Amid U.S.-EU semiconductor localization mandates, reliance on American IP or tools could trigger export compliance scrutiny for foundries in Taiwan, China and South Korea, inflating supply chain redundancy costs. Countering Teradyne’s early lead in co-packaged optics testing, Advantest aims to lock in OpenLight’s PDK ecosystem as a strategic moat. Within 18 months, as NVIDIA and Meta ramp 800G/1.6T optical modules, second-tier OSATs lacking native SiPh test capabilities will likely be squeezed out of the high-end market, accelerating industry consolidation.
