The rapid expansion of artificial intelligence (AI) and machine learning (ML) applications requires effective connectivity between processing units and high-speed transmission. It has increased interest in optical interconnects, especially for short-range connections between XPUs (CPUs, GPUs, and memory). When compared to conventional methods, silicon photonics is showing promise as a technology for enhanced performance, cost-effectiveness, and thermal management capabilities that eventually improve the functionality of AI/ML systems.
For AI/ML systems, which need fast data sharing, low power consumption, and high computing density, interconnects are essential. Laser integration allows light signal production and manipulation, while silicon photonics enhances communication between memory and computer units.
Beyond typical electrical interconnects, companies are investing in on-chip optical interconnects to provide scalability from one laser to hundreds. High-speed data transport with reduced power consumption and enhanced thermal efficiency is made possible by silicon photonics technology. In addition, this technology enables stronger coupling, lower power consumption, increased thermal efficiency, and high-density bandwidth connections.
By eliminating the need for externally connected lasers and lowering operating and capital costs, silicon photonics provides a financially viable alternative for backend production. Merging active components raises the overall bandwidth per photonic integrated circuits (PICs). Additionally, silicon photonics enables effective data transport in AI/ML applications, improving real-time system performance and decision-making.
