Photonics is undergoing the same transformation the semiconductor industry experienced decades ago; evolving from specialized, low-volume manufacturing into standardized, highly automated, high-volume production.
 

For decades, electrical interconnects have been the foundation of modern computing. However, as AI workloads drive exponential growth in bandwidth while power budgets remain constrained, copper is approaching its physical and economic limits. Higher data rates demand more power, generate more heat, and make signal integrity increasingly difficult to maintain. As a result, the industry can no longer rely solely on electrical connections to continue scaling computing performance.

Optical interconnects have therefore evolved from an emerging technology into a strategic necessity. By transmitting information with light instead of electrical signals, silicon photonics enables significantly higher bandwidth density, lower latency, improved signal integrity, and greater energy efficiency. These advantages are accelerating the adoption of photonic integrated circuits (PICs), optical I/O, co-packaged optics, and other optical networking technologies that are reshaping AI infrastructure and hyperscale data centers.

Despite remarkable advances in photonic device design, one major challenge remains: manufacturing at scale.

As production volumes increase, testing and packaging have become the primary economic bottlenecks. Active optical alignment, optical characterization, fiber attachment, and final assembly represent a significant portion of manufacturing cost and cycle time. The challenge is no longer proving that silicon photonics works; it is manufacturing it with the throughput, yield, and cost required for next-generation AI infrastructure.

This podcast explores how precision motion, intelligent alignment, and automation technologies are enabling that transition by transforming photonics manufacturing from a serial, labor-intensive process into a highly automated, high-throughput production environment, making large-scale deployment of optical interconnects both practical and economically viable.
