As AI workloads push data center architectures beyond the capabilities of electrical interconnects, photonics is no longer a peripheral technology. It is being pulled into the core of system design—reshaping how compute, memory, and networking are integrated at the semiconductor level.

This transition is inseparable from heterogeneous integration. As performance, power, and bandwidth density constraints tighten, optical functions are moving closer to silicon through platforms such as silicon photonics, and architectures such as co-packaged optics (CPO) and optical I/O (OIO). These are not incremental upgrades, but structural responses to system-level pressure.

Fourtonics focuses on this convergence—where semiconductor scaling limits, photonics, and integration technologies intersect—to understand why optical interconnects are becoming system-critical, and how this shift represents a long-duration, structural growth opportunity for the photonics industry as it becomes increasingly central to the electronics and semiconductor ecosystem.
