Ayar Labs to Accelerate Development and Application of Optical Interconnects in AI/ML Architectures with NVIDIA

Revolutionizing Chip-to-Chip Communication

Ayar Labs is disrupting the traditional performance, cost, and efficiency curves of the semiconductor and computing industries by delivering up to a 1000x improvement in interconnect bandwidth density at one-tenth the power. We use standard CMOS processing to develop high-speed, high-density, low-power optical interconnect “chiplets” and lasers to replace traditional electrical I/O.

Ayar Labs Demonstrates the Industry’s First 4 Tbps Optical Solution for Chip-to-Chip Connectivity

At OFC 2023, Ayar Labs showcased its CW-WDM optical I/O solution moving data from one TeraPHY™ optical I/O chiplet to another TeraPHY chiplet at 2.048 Tbps, powered by SuperNova™ light sources. Each SuperNova light source powers 8 optical ports in each TeraPHY I/O chiplet. With 8 precisely spaced wavelengths modulated at a data rate of 32 Gbps, each optical port delivers 256 Gbps of bandwidth. Each TeraPHY chiplet therefore provides a throughput of 2.048 Tbps in each direction, or 4.096 Tbps bidirectional.

Fabricated in the GF Fotonix process, the electro-optical transceivers in the TeraPHY chiplet are fully integrated and achieve error-free data transmission without FEC (forward error correction). Perhaps more importantly, the data transfer consumes less than 5 pJ/bit, providing the power density and performance per watt needed to achieve trillions of AI connections in advanced HPC designs and more.

Optical I/O: Designing the Future of Digital Beamforming and Antenna Arrays

Digital beamforming, which uses a large number of elements in antenna arrays, is the core technology driving advanced radar and communications systems for the aerospace industry. Phased array radar demands increasingly higher fidelity, which requires more elements generating more data. Only optical I/O from Ayar Labs provides the bandwidth density needed to deliver precise, higher fidelity phased array radar.

SWaP-Friendly Architectures Using Digital Beamforming and Optical I/O

The power and sophistication of modern radar systems is growing by leaps and bounds. These systems already offer capabilities that couldn’t have been dreamed of just a few short years ago. Furthermore, ongoing developments mean that these systems are poised to revolutionize sensing applications. However, there is a data bandwidth bottleneck that must be overcome to take full advantage of these state-of-the-art technologies.
