Okres sprawozdawczy: 2024-03-01 do 2025-08-31
Modern society faces unprecedented demand for data processing driven by artificial intelligence, autonomous systems, data centers, and emerging quantum technologies. These applications require computing systems that are not only faster but also dramatically more energy-efficient than current technologies. Photonic integrated circuits—chips that process information using light rather than electrons—offer a promising path forward, but existing approaches for making these circuits programmable often suffer from high power consumption and thermal management challenges.
NeuroPIC addresses this fundamental challenge by exploring alternative approaches to programmable photonics that offer the potential for significantly reduced power consumption compared to conventional technologies while providing compact footprints and potentially faster operation. Recent technological advances now make it feasible to explore these concepts at larger scales, opening possibilities for programmable photonic processors that were previously impractical.
The project pursues several interconnected technical objectives spanning advanced nanofabrication, scalable programmable photonic platforms, high-density optical interconnection technologies, and neuromorphic computing implementations. These objectives aim to demonstrate that programmable photonic circuits can perform complex information processing tasks with improved energy efficiency compared to existing solutions. A key scientific goal is exploring neuromorphic computing—brain-inspired information processing—using photonic systems with nonlinear dynamics. This research investigates fundamental questions about how physical complexity and nonlinearity contribute to computation, potentially revealing new principles for next-generation computing architectures beyond conventional digital approaches.
