The HUMMINGBIRD by Lightelligence is an innovative optical Network-on-Chip processor that integrates photonic and electronic dies through advanced vertically stacked packaging technologies. This architecture provides a pathway to overcome conventional digital network limitations, particularly the 'memory wall.' With a 64-core domain-specific AI processor, HUMMINGBIRD uses a cutting-edge waveguide system to propagate light-speed signals, drastically reducing latency and power requirements compared to traditional electronic networks. This high-performance device serves as the communication backbone for data centers, facilitating data management and interconnect topology innovations. HUMMINGBIRD exploits the power of silicon photonics to offer a dense all-to-all data broadcast network that enhances the performance and scalability of AI workloads. HUMMINGBIRD's robust integration into PCIe form factors allows easy deployment onto industry-standard servers, and when paired with the Lightelligence Software Development Kit, it can significantly optimize AI and machine learning processes. This integration fosters a higher utilization of computing power and alleviates complexities associated with mapping workloads to hardware.
Moonstone, an offering from Lightelligence, is a highly versatile laser source available in both single and multi-wavelength configurations. Unlike conventional laser packages, Moonstone features a compact design and enhanced temperature management, making it a cost-effective and modular solution for diverse applications including telecommunications, LiDAR, and sensor technologies. The product leverages an automated optical packaging process that integrates off-the-shelf laser chips with the Moonstone carrier through advanced techniques like eutectic soldering and die-bonding. The ensuing laser assembly enables a free-space coupling method for single wavelength use, and a multiplexing approach for multi-wavelength scenarios, optimizing optical signal combination and transmission efficiencies. Moonstone's precision engineering and thermal regulation provide low coupling losses and high output power, suitable for demanding environments where high-speed and high-bandwidth data transmission are crucial. It serves a vital role in optical computing, offering substantial power delivery while maintaining a low phase noise footprint, thus bolstering AI computational capacities significantly.
Photowave is Lightelligence's contribution to the realm of optical communications, specifically designed for connectivity solutions like PCIe and Compute Express Link (CXL). This optical hardware capitalizes on the inherent low latency and energy-saving attributes of photonics, allowing for extensive scalability across server racks, crucial to modern data centers. Photowave is a trailblazer, marking the first optical interconnect tailored for CXL setups, providing a remarkable latency of less than 1 nanosecond in Active Optical Cables and slightly more in other configurations. It supports advanced CXL standards and PCIe 5.0 speeds, making it a desirable choice for future-proofing data center infrastructures. Additionally, Photowave proves advantageous in AI data centers, demonstrating significant throughput improvements in memory-intensive tasks such as large language model applications. Through its robust construction and innovative use of multi-mode fibers, Photowave assures a 2.4x improved performance in memory offloading tasks, offering constant high performance levels not seen in traditional disk-based architectures.
Lightelligence's PACE is an advanced photonic computing platform that integrates a 64x64 optical matrix multiplier into a silicon photonic chip alongside a CMOS microelectronic chip. This fully integrated system employs sophisticated 3D packaging technology and contains over 12,000 discrete photonic devices. The PACE platform is designed to operate at a system clock of 1GHz, making it ideal for ultra-low latency and energy-efficient applications. The platform's architecture is powered by the Optical Multiply Accumulate (oMAC) technology, which is essential for performing optical matrix multiplications. Input vectors are initially extracted from on-chip SRAM and converted into analog values, which are then modulated optically. The resulting optical vector propagates through an optical matrix to generate an output vector, which undergoes conversion back to the digital domain after being detected by an array of photodetectors. PACE aims to tackle computational challenges, particularly in scenarios like solving Ising problems, where interactions are encoded in an adjacency matrix. The photonic processing capabilities of PACE are geared towards speeding up numerous applications, including bioinformatics, route planning, and materials research, promising significant breakthroughs in chip design and computational efficiency.
