About
CogniFiber is an Israeli startup developing DeepLight processors that utilize multi-core optical fibers to process data at the speed of light, aiming to increase processing speeds up to 1,000 times during AI inference while using only about 1% of the energy. The company's platform offers neuromorphic neural networks embedded in optical fibers and glass chips and multicore processing architecture, enabling data centers and high-performance computing operators to improve workload efficiency while reducing energy usage and operational costs. CogniFiber's approach is purely photonic, eliminating the overhead of converting between optical and digital domains. Their solutions save over 90% of compute energy and reduce heat dissipation by over 90%, contributing to sustainable AI applications.
