Aerospace giants like Raytheon and Lockheed Martin see optical I/O advancing multiple SWaP-constrained applications like digital beamforming, phased array radar, and disaggregated airborne systems. For example, aerospace designers can architect disaggregated systems—placing sensors on the wings and nose of a jet and employing lightweight, EMI-resistant optical interconnects to quickly move data to processing units in the center of the plane.

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

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

Cloud and Data Center

Major cloud and data center service providers are looking to optical I/O to deliver new innovations in system designs, such as disaggregated architectures that allow matching resources to workloads. Companies such as Intel, Google, and HPE see opportunities for multiple applications for their customers in terms of increased bandwidth, performance, and flexibility while reducing power consumption.

Artificial Intelligence

Optical I/O enables disaggregated architectures that decouple memory from processors and accelerators, allowing memory to be pooled with low latency and high performance. These new architectures provide flexible designs that can be shifted to meet the demands of ever-increasing AI workloads. NVIDIA believes optical I/O is a key technology on the path to its next million-X speedup in AI.

Ayar Labs’ optical I/O unleashes the potential of next-generation AI compute architectures

Generative AI is enabling transformative outcomes, but model complexity is growing exponentially. Traditional interconnects create a bottleneck for data, forcing GPUs to remain idle a majority of the time. We need a new approach to generative AI architecture: optically connect nodes at scale so they effectively work like a single, giant GPU.

Ayar Labs’ Optical I/O Enables Disaggregated Architectures for Cloud, AI, and HPC

Disaggregated architectures are shifting the paradigm of innovation by enabling resource composability for more efficient utilization in Cloud, AI, and high performance computing.

High Performance Computing

Ayar Labs’ in-package optical I/O delivers up to 1000x bandwidth density improvements at one-tenth the power compared to electrical I/O. Future generations of HPE Slingshot, a high-performance Ethernet fabric specifically designed for HPC and AI solutions, plan to include optical I/O to deliver unprecedented bandwidth and speed, at lower levels of power and latency, to meet customers‘ growing demands for scale and performance.

Bottlenecks to Unleash Innovation

Ayar Labs is the first to deliver monolithic in-package optical I/O (OIO) chiplets, a new universal I/O solution that enables chips to communicate with each other from millimeter to kilometer-scale, at the power, latency, and bandwidth density of in-package interconnect. Several technology trends point to the arrival of OIO chiplets as a critical industry inflection point…

Scalable and Sustainable AI: Rethinking Hardware and System Architecture

In this webinar panelists discuss the challenges of scaling up AI workloads on existing architectures and the emerging solutions that can dramatically improve performance, efficiency, and scalability. Moderated by EE Times, the webinar features panelists from Ayar Labs, Google, Lawrence Berkeley National Laboratory, NVIDIA, and Tenstorrent.


Optical I/O is also key for digital beamforming in telecom applications. Digital beamforming uses a large number of elements in antenna arrays to generate tightly directed beams for communication. OIO enables more elements in each antenna as well as more antennas in the same footprint to move a quadratic increase in data.
