About

Neurophos is a startup developing high-performance, energy-efficient photonic chips specifically designed for AI inference. The company aims to address the significant power consumption and scalability limitations of traditional silicon-based GPUs in data centers by using optical processing. Their technology is positioned as a next-generation solution for the growing demands of AI infrastructure.

Neurophos stands out by using a physics-based approach with metasurface modulators on its photonic chips, which enables massive parallelism with optical elements 10,000 times smaller than previous technologies. This innovation overcomes the power-wall limitations of silicon, promising significant gains in speed and energy efficiency.

Product

Optical Processing Unit (OPU)

Photonic AI Accelerator

The flagship product is the Optical Processing Unit (OPU), a photonic chip that integrates over one million micron-scale optical processing elements. It leverages metasurface modulators to perform matrix-vector multiplication, a fundamental operation in AI inference, using light instead of electricity to achieve superior performance.

  • Offers up to 100x improvements in performance and energy efficiency over traditional GPUs
  • Operates at 56 GHz, delivering 235 Peta Operations per Second (POPS) with a power consumption of 675 watts
  • Features extremely small optical elements, enabling massive parallelism

Built for

The primary customer segments are AI labs, hyperscalers, and large-scale data center operators.
