Lucas and Luna explore how on-chip optical interconnects are breaking the bandwidth bottleneck in data centers and AI accelerators. They focus on a specific 2025 breakthrough: a CMOS-compatible silicon photonic transceiver from a joint Ayar Labs and Intel prototype, capable of 2 Tbps per fiber. Lucas explains why electrical interconnects hit a wall around 50 pJ/bit, while optical links drop below 1 pJ/bit. Luna questions integration challenges—thermal stability, laser packaging—and Lucas walks through the hybrid laser bonding technique. They tie it to the exploding demand for memory bandwidth in large language model training, and discuss why this tech is finally ready for production, with volume sampling expected in 2027. No fluff, just concrete engineering. #OnChipOpticalInterconnects #SiliconPhotonics #AyarLabs #Intel #DataCenter #AIAccelerators #BandwidthBottleneck #CMOSCompatible #HybridLaserBonding #MemoryBandwidth #LLMTraining #2Tbps #PhotonicTransceiver #ChipletInterconnect #Technology #Engineering #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
