About CogniFiber
CogniFiber is an Israeli startup developing optical computing hardware, meaning it processes information with light instead of electrical current. Its DeepLight design uses multi-core optical fibre to carry out neural network calculations as light passes through, which avoids repeated reads and writes to separate memory. The company says this could cut the energy needed for AI inference, but the figures come from the company and are not independently confirmed. It was founded in 2018 by Eyal Cohen and Zeev Zalevsky.
CogniFiber was founded in 2018 and is based in Rosh HaAyin, Israel. It is listed under Photonic Computing, AI Accelerators.

What CogniFiber works on
Photonic Computing
Photonic computing uses light instead of electricity to carry or process information. Photons have no charge, so light in a waveguide does not cause the resistive heating that current in a wire does, though lasers and modulators still use power, and many wavelengths can share one waveguide. The industry has two quite different parts: moving data with light, and computing with light.
AI Accelerators
An AI accelerator is a chip, or a part of a chip, designed to run machine learning faster or with less energy than a general-purpose processor. The category includes GPUs, TPUs, neural processing units (NPUs) and chips from many startups.
