Who we are

Lightmatter is a computer hardware company that uses integrated photonics to create faster and more efficient processors. We accelerate critical operations in deep neural networks using an array of programmable photonic elements fabricated alongside transistors in conventional CMOS processes (the same processes used to make cell phone chips). Advantages of our optical processing technology include speed of light evaluations as well as low power consumption. By accelerating this core AI operation, we can speed up many of the software algorithms underlying image recognition, natural language processing, and more, thereby facilitating the next generation of AI-powered computing.
