Yole: Leveraging optical chip-to-chip connectivity to unleash the complete potential of AI – An interview with Ayar Labs

Co-packaged optics (CPO) has gained attention recently due to its power efficiency in data centers. While most leading proponents of CPO targeting networking applications have discontinued CPO programs due to macroeconomic headwinds, the situation of CPO for artificial Intelligence (AI) and machine learning (ML) systems is different. 

Optical I/O Glossary

What’s a microring resonator? What’s a chiplet? What’s an optical interconnect? If you’re finding ever-changing silicon photonics and optical I/O terms confusing, check out our new glossary. Each definition includes links to white papers, blogs, and videos for a deeper dive. We’ll be adding more terms over time.


Disaggregation and Optical Interconnect in AI/HPC Networks

This webinar discusses the push towards disaggregated resources and optical interconnect technologies to enable the next generation of high performance computing (HPC) and artificial intelligence infrastructure. Partners throughout the ecosystem will provide their perspective on the latest advances, from foundry to optical interconnects, to systems and cloud services. In addition, a test and measurement perspective will be provided to support this new wave of interconnect technology.

Advancing Aerospace Applications with Optical I/O

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.
