Rewiring AI: How Ayar Labs’ Optical I/O is Outshining the Competition
- Ayar Labs was founded in 2015 and is funded by several domestic and international venture capital firms as well as strategic investors.
- Ayar Labs is driving a 1000x improvement in interconnect bandwidth density at 10x lower power.
- Its patented approach uses industry-standard, cost-effective silicon processing techniques to develop high-speed, high-density, low-power optical-based interconnect “chiplets” and lasers to replace traditional electrical-based I/O.
In the fast-paced world of artificial intelligence (AI), speed and efficiency are important.
As AI models grow larger and more complex, traditional electronic communication systems that rely on copper-based interconnects struggle to keep up. Ayar Labs’ optical I/O technology uses light to transmit data between processors.
Founded in 2015, Ayar Labs was established by a team that includes Mark Wade, Milos Popovic, Vladimir Stojanovic, Chen S., Alex Wright-Gladstein, and Rajeev Ram.
The Power of Ayar Labs Optical I/O Technology
Data transfer has long relied on electrical signals transmitted through copper wires. Ayar Labs uses optical I/O technology to transmit data with light.
The company’s approach uses optical-based interconnect “chiplets” and lasers developed with silicon processing techniques. The technology drives a 1000x improvement in interconnect bandwidth density at 10x lower power.
“Ayar Labs represents the future of interconnects which have eventual applicability to every electronic device on earth”, said Warren Rogers, partner and head of Ventures at Downing Ventures, in a statement. “We have the highest confidence that when their optical I/O technology is applied to computing, the industry will finally break away from Moore’s Law and redefine the boundaries of computing.”
Boosting AI With Optical Interconnects
Ayar Labs’ optical interconnect technology is making a difference in the AI industry. The company’s solutions help data move more freely and efficiently between processors and scale AI models faster.
The technology unlocks greater potential for AI applications, from autonomous vehicles to large-scale data analytics.

One of Ayar Labs’ core advantages is its partnerships with industry giants like Intel and NVIDIA, enabling adoption of optical I/O technology in next-generation AI hardware.
Ayar Labs’ Strategic Investments and Funding
Ayar Labs raised $35 million in 2020. In 2022, the company raised a $130 million Series C round. Ayar Labs raised $155 million in a Series D round on December 11, 2024.
The funding supported Ayar Labs’ development of in-package optical I/O solutions, which the article describes as the first of their kind in the industry.
The leadership team includes Pooya Tadayon, described in the article as a former Intel veteran leading packaging and test development.
Ayar Labs and OFC 2024
Ayar Labs showcased its optical interconnect solutions at the Optical Fiber Communication Conference in San Diego on March 24–28, 2024.
Ayar Labs announced a partnership with Wiwynn for a joint AI co-packaged optics solution to be showcased at OFC 2026.
