Semiconductors · Boulder, United States · Founded 2024

Revolutionizing computing with photonics, superconductors, and semiconductors for intelligence at physics' boundaries MoreLess

Great Sky is pioneering a new era of computing by integrating photonics, superconductors, and semiconductors to create hardware that operates at the theoretical limits of speed and efficiency. The company is focused on developing a novel architecture that mimics the essential structure of a brain, condensed into a compact chip-scale network. This approach enables the execution of sophisticated analog neural networks, with the potential to perform more synapse operations per second than the human brain. Great Sky's technology is set to evolve into wafer-scale networks, where a single 300 mm wafer can host an entire network, unlocking new capabilities. By interconnecting these wafer-scale networks, the company aims to construct multi-modular cognitive systems, emulating key brain modules such as the thalamus, hippocampus, and neocortex. Since its inception in 2014, Great Sky has made significant strides, including the development of silicon LEDs and multiplanar waveguides, which are crucial for efficient optical communication within its platform. The company's business model revolves around leveraging these technological advancements to serve industries that require high-speed, efficient computing solutions, potentially transforming sectors reliant on advanced neural network processing. Keywords: photonics, superconductors, semiconductors, neuromorphic, wafer-scale, synapse operations, cognitive systems, brain modules, optical communication, neural networks.
