PXI: The Way Forward for High-Volume Photonic IC Testing

In this white paper, we explore the role of Photonic Integrated Circuits (PICs) in meeting the bandwidth demands of AI and data-intensive applications, and as the industry shifts from R&D to high-volume manufacturing, testing these devices becomes a critical challenge. Traditional test setups are not scalable or efficient enough for mass production. The PXI platform, a well-established standard in electronic IC testing, offers a compelling solution for PIC testing at scale. Its modular, compact, and hybrid design enables dense, cost-effective, and synchronized testing—making it ideal for high-throughput PIC manufacturing environments.
