Lightmatter announced the launch of Passage M1000, a 3D Photonic Superchip designed to meet the demands of next-generation AI infrastructure. The Passage M1000 sets a new benchmark with an unprecedented 114 Tbps total optical bandwidth, making it the world's fastest AI interconnect.
The Passage M1000, with its expansive 4,000 square millimeter multi-reticle active photonic interposer, enables the largest die complexes in a 3D package. This innovation provides seamless connectivity to thousands of GPUs within a single domain, overcoming the bandwidth limitations of traditional electrical I/O connections.
Key Features :
8-tile 3D active interposer with an integrated programmable waveguide network.
3D integrated electrical circuits containing 1024 Electrical SerDes.
56 Gbps NRZ modulation and 8 wavelength WDM transmission on waveguides and fibers.
256 optical fibers edge-attached, delivering 448 Gbps bandwidth per fiber.
1.5 kW power delivery in an advanced integrated package (7,735 mm²).
Lightmatter has worked closely with GlobalFoundries (GF) and packaging expert Amkor, to ensure production readiness for customer designs based on the M1000 reference platform. The Passage M1000 leverages the GF Fotonix silicon photonics platform from GlobalFoundries, integrating photonic components with high-performance CMOS logic into a single die. This collaboration ensures production readiness and scalability to meet the growing demands of AI applications.
Nick Harris, founder and CEO of Lightmatter, stated, "Passage M1000 is a breakthrough achievement in photonics and semiconductor packaging for AI infrastructure. We are delivering a cutting-edge photonics roadmap years ahead of industry projections."
Dr. Thomas Caulfield, president and CEO of GlobalFoundries, added, "The M1000 photonic interposer architecture, built on our GF Fotonix platform, sets the pace for photonics performance and will transform advanced AI chip design."
The Passage M1000 and the newly announced Passage L200 are set to accelerate AI advancements by enabling larger and more capable AI models to be trained faster than ever before. The Passage M1000 will be available in the summer of 2025, alongside Lightmatter's powerful light engine.
