TIWhat if computers stopped using electricity and started using light…?🤯
We’ve hit a wall with silicon chips.
Electrons can only move so fast and that’s what limits how quickly today’s GPUs can train AI.
So researchers are building optical neural networks processors that compute using light, not electricity.
They replace transistors with photonic circuits made of waveguides, mirrors, and modulators.
When beams of light intersect, they perform calculations…addition, multiplication literally as light waves interfere.
But how can light actually do math?
Each laser pulse represents a number.
When two pulses overlap, their amplitudes combine the foundation of matrix multiplication in neural nets.
Companies like Lightmatter are already building these chips that can train AI 1,000× faster with a fraction of the power.
