Problem
Traditional silicon-based chips face physical limitations in transistor density, leading to increased size and power consumption, which hinders the scalability required for advanced AI applications. The ability to connect numerous chips with high bandwidth and low latency is crucial for achieving artificial general intelligence (AGI), but current interconnect technologies struggle to meet these demands.
Solution
Lightmatter develops photonic processors and interconnect technology to overcome the limitations of conventional silicon chips, enabling the creation of larger, more powerful computing systems for AI. Their Passage technology facilitates high-bandwidth, low-latency connections between multiple chips, allowing for extreme scaling and improved performance. By integrating photonics with advanced packaging, Lightmatter enables the construction of wafer-scale systems with increased silicon area per package. This approach blurs the lines between scale-up and scale-out networks, paving the way for the development of AGI.
