Co-Packaged Optics: the Future of AI Infrastructure Scaling

The rapid advancement of artificial intelligence is driving a shift from traditional compute architectures toward large-scale distributed clusters that function as a unified engine. This systemic approach necessitates new interconnection technologies to support increasingly large models.

Scaling Strategies and Optical Integration

Data center infrastructure for AI employs two scaling strategies. While scale-out networks are beginning to use co-packaged optics in switches to reduce signal loss and power use, the next step involves integrating silicon photonics into the scale-up layer to move beyond the limits of copper cables.

The placement of optical engines has evolved from front-panel transceivers to integration closer to or within the same package as switch chips. This shortens electrical pathways, yielding benefits for bandwidth, power, and scalability. Over the past five years, progress in electronic and photonic integrated circuits within these engines has resulted in a sixty-four-fold rise in bandwidth density and a fivefold gain in energy efficiency.

Challenges in Co-Packaged Optics Implementation

Despite targeting lower energy use per bit than conventional pluggable transceivers, and scaling to high bandwidths, co-packaged optics faces significant hurdles for mass production. A major challenge is a bandwidth density mismatch between AI chiplets and current optical interconnects, with a six-fold gap present.

This gap highlights a need for photonic integrated circuits with smaller form factors and scalable fiber array units. Creating compact, detachable fiber arrays is difficult due to fiber pitch dimensions. While multiplexing technologies can lower fiber count, maintaining wavelength stability across temperature changes is problematic.

The assembly process for co-packaged optics is intricate, combining components like lasers, optics, fiber arrays, and silicon circuits from different wafer nodes. Two primary integration methods are being explored: one positions the photonic circuit atop the electronic circuit, while another places it below, using vertical interconnects. The latter approach offers better thermal performance and supports very high data rates per lane, making it suitable for demanding applications.

Manufacturing and Testing Hurdles

Manufacturing inconsistencies necessitate active alignment processes to optimize optical coupling, which are time-consuming. The permanent bonding used in conventional optics makes repair impossible if a fiber fails. The industry is moving toward detachable fiber array solutions for better reparability, but these struggle with alignment precision and repeatability in high-volume production. One potential solution uses wafer-level optical couplers to increase coupling tolerance.

Maintaining yield requires qualifying optical engines before final assembly, ideally through double-side wafer-level testing. However, this method is not compatible with all integration configurations. For some 3D configurations, the thin photonic circuits require reinforcement to withstand the mechanical forces of testing equipment.

The Path Forward

The evolution of AI infrastructure through co-packaged optics and heterogeneous integration presents both promise and difficulty. Next-generation solutions will need substantial gains in bandwidth density and energy efficiency. The concept of known-good optical engines is vital for high yield, requiring designs compatible with automated testing and pluggable socket forces. Overcoming these challenges is seen as requiring collaboration across the semiconductor ecosystem, from circuit designers to packaging experts and system integrators.
