ams OSRAM unveils 850nm thin-film micro-VCSEL arrays for AI scale-up
ams OSRAM AG of Premstaetten, Austria, and Munich, Germany has unveiled its latest thin-film VCSEL for AI scale-up, showcasing a connectorized multi-core fiber solution and expanding the ecosystem network.
As artificial intelligence continues to drive unprecedented growth in computing infrastructure, moving data efficiently is becoming just as critical as processing it, notes the firm. The increasing scale of AI training and inference clusters is placing new demands on optical interconnect technologies, requiring higher bandwidth, lower latency and significantly improved power efficiency.
To address this emerging opportunity, ams OSRAM is expanding its Digital Photonics strategy. Building on its expertise in intelligent light emitters, optical sensors and advanced semiconductor manufacturing and assembly, the firm is unveiling key photonic building blocks required for next-generation AI infrastructure. These include addressable micro-emitter arrays based on both LED and VCSEL technologies, as well as matching micro-photodiode arrays that together form the optical foundation of future ultra-high-bandwidth interconnect architectures.
In booth #1281 at the European Conference on Optical Communications (ECOC 2026) in Málaga Spain (21–23 September), ams OSRAM is unveiling its latest thin-film VCSEL technology and demonstrating a connectorized multi-core fiber solution in collaboration with BizLink, maturing the ecosystem for highly parallel, ultra-low-power optical interconnects for AI scale-up.
Building a wide-and-slow ecosystem for AI infrastructure
Following the strategic customer cooperation announced earlier this year with a confidential industry partner, ams OSRAM continues to broaden its ecosystem for wide-and-slow optical interconnect architectures.
It is collaborating with multiple partners across the value chain, including testing, fiber infrastructure, connector technologies, packaging and system integration, with the objective of accelerating industry adoption of next-generation optical interconnect solutions.
BizLink joins this growing ecosystem as a specialist in optical connectivity and connector solutions and is supporting the development of the ECOC demonstrator.
From adaptive headlamps to AI data movement
ams OSRAM’s says that the foundations of its optical interconnect technology were established long before the emergence of today’s AI infrastructure market.
ams OSRAM’s optical interconnect technology builds on the same core technology platform that enabled the commercialization of the EVIYOS digital lighting solutions.
Combining highly addressable micro-emitter arrays, CMOS integration, wafer-level manufacturing know-how and advanced packaging technologies, EVIYOS has demonstrated the scalability and manufacturability of ams OSRAM’s Digital Photonics platform in high-volume production. The platform has also proven ams OSRAM’s ability to serve demanding markets requiring consistent quality, reliability and production scalability across millions of devices.
The same technology principles are now being extended into AI infrastructure as well as mobile/wearable applications. What began as a highly addressable micro-emitter architecture for adaptive headlamps is evolving into a photonics platform capable of moving data with exceptional energy efficiency and scalability.
Re-thinking optical interconnects with wide-and-slow architectures
The rapid scaling of AI clusters is reshaping requirements for intra-datacenter connectivity. Future AI scale-up networks will require interconnects that simultaneously optimize power consumption, latency, density, reliability and cost.
ams OSRAM is targeting this challenge through a highly parallel wide-and-slow optical architecture. Instead of transmitting increasing amounts of data through a limited number of highly complex channels, data is distributed across a large number of lower-speed optical lanes. Realizing such highly parallel architecture also requires corresponding advances in fiber and connector technologies, highlighting the critical importance of the ams OSRAM and BizLink partnership.
This approach reduces overall system complexity while enabling lower latency, lower power consumption and scalable bandwidth growth. As AI clusters continue to expand, the wide-and-slow architecture offers a promising path toward more sustainable and cost-efficient infrastructure, says ams OSRAM.
Thin-film micro-VCSEL platform for AI scale-up networks
ams OSRAM continues to expand its photonics portfolio through the development of a next-generation 850nm thin-film VCSEL platform specifically designed for AI scale-up interconnects.
The platform combines several differentiating technologies in a single architecture, including top-emission thin-film VCSELs, dense 25µm-pitch micro-VCSEL arrays with addressability, silicon TSV integration and compatibility with standard multi-mode fiber infrastructure. This enables highly parallel optical links with exceptional packaging density and ultra-low-power operation.
The firm has completed micro-VCSEL integration on silicon TSV substrates and demonstrated error-free 32Gb/s NRZ operation. The platform achieves an energy efficiency of about 0.25 pJ/bit while maintaining compatibility with scalable manufacturing approaches. This level of efficiency highlights the potential of highly parallel optical architectures to support future bandwidth scaling while minimizing power consumption.
In addition, reliability testing has shown no failures after more than 2000 hours under elevated junction temperatures and current overstress conditions.
Building on these results, ams OSRAM is advancing the development of fully integrated 3D photonics stacks combining micro-VCSEL arrays, micro-photodiode arrays and mixed signal CMOS electronics for future ultra-high-bandwidth optical interconnect architectures.
ECOC 2026 demonstrates high-speed operation with a connectorized fiber solution
At ECOC 2026, ams OSRAM is presenting its most advanced optical interconnect demonstrator to date together with BizLink, a provider of interconnect, fiber-optic connectivity and optical integration solutions.
The demonstrator combines ams OSRAM's 2D addressable 850nm micro-VCSEL array technology with BizLink’s fiber-array integration and optical connectivity expertise, creating a connectorized multi-core fiber solution optimized for wide-and-slow data communication.
The system will be demonstrated in a private setting for selected customers and industry partners during the event.
“AI infrastructure requires a fundamentally different approach to moving data, and wide-and-slow optical architectures deliver a step-change in power efficiency, latency and scalability,” says Ashkan Seyedi, VP & general manager of Optical Interconnects at ams OSRAM. “As an integrated electro-optical engine provider, it’s our role to build out the ecosystem required to support a scalable industry solution, and we’re excited about our partnership with BizLink to enable fiber connectivity solutions,” he adds.
“This demonstrator validates a fundamentally different optical interconnect architecture optimized for ultra-low power and low latency operation,” notes Hendrik Coldenstrodt, chief technology officer of the Computing and Transportation business group at BizLink Group. “By combining ams OSRAM’s addressable micro-VCSEL technology with BizLink’s expertise in fiber-array integration, optical packaging and manufacturing, we have demonstrated the potential of highly parallel optical interconnects for future AI infrastructure.”
