PHASER
A neural accelerator that runs at the speed of light.
Designed around parts the telecom and display industries already make by the million. No new fabs, no exotic materials, and no new power plants.
01 / The light
Intelligence runs on electrons.PHASER runs it on light.
less energy per step than a GPU.Modeled at one megapixel of optics · not yet built
02 / The machine
Optical computation
Algorithms are mapped onto the diffusion process photons perform as they bounce within a resonance chamber.
One step: ten trips of light between two mirrors 10 cm apart.
Each pass is programmed. Here, one pass is one step of an image model: noise in, less noise out.
steps per second from one stack: 67 wavefronts in flight, 10 ps apart, 100 GHz in and out.
Pushing charge through a wire costs energy every time. Light passing through glass doesn’t: it interferes with itself on the way through, and that interference is the arithmetic. PHASER only pays to keep the light going.
03 / The world
AI is running out of electricity.
