AI Accelerated Computing

Scaling CMOS-based processors is increasingly challenging due to the slowdown of Moore's Law and the breakdown of Dennard scaling; data movement with electronic wires (capacitive loss) limit clock speeds and lead to thermal dissipation.

Opticore patented optical processing units (OPUs) are designed to handle memory-intensive AI tasks with on-chip data movement and computation with photonic integrated circuits. Our prototype achieves 100x higher energy efficiency and 100x greater computing density than digital electronics. Fully integrated with foundry-based, co-packaged optoelectronics, the system promises to lead breakthroughs in the next era of high performance computing in data centers.
