Episode How On-Chip Silicon Photonics Are Shrinking Data Centers
Episode 142 of The Hardware Podcast dives into silicon photonics—the technology replacing copper wires with light inside data centers. Lucas and Luna break down why we're hitting a bandwidth wall, how companies like Intel and Broadcom are shipping optical engines on chip, and what this means for power consumption and AI clusters. They explore the physics of waveguides, modulators, and photodetectors, and how manufacturing silicon photonics leverages existing CMOS fabs. The episode also touches on the economics: why optical interconnects are dropping in cost and where co-packaged optics will land next. If you're curious about the hardware that will make future AI models possible, this episode is for you.
