In-house developed silicon photonics & ICs
Unique silicon photonics, light sources, optical interposers, mixed-signal ICs – designed for superior yield and reliability.
Single platform & software architecture
The LumiCoreTM Platform powers pluggables, NPO, and CPO – each feeding the data pipeline and feedback loop.
Ownership of manufacturing test, process and robotics
Lumilens owns its process recipes, automation, test equipment design, and MES — resulting in very high-volume manufacturing and quality.
Why Lumilens is different
LumiCore™ platform
LumiCore is a fully integrated silicon platform -- photonics, mixed-signal ICs, electrical-optical interposers, and optical systems – that enables faster development, tighter integration for high-volume manufacturing, and better supply chain control
Tech that’s designed for HVM
Lumilens leverages unique silicon photonics, high power light sources, electrical-optical interposers – all designed for high-volume production, yield, reliability and superior margins. Multiple patents pending.
System-level knowledge
In addition to broad component-level expertise, Lumilens brings deep systems-level experience that provides strong value in developing customized scale-up architectures
Smooth transition from NPO to CPO
Lumilens provides hyperscalers with the ability to drive early adoption of scale-up using NPO and smoothly transition to full CPO over time, leveraging the common LumiCore silicon platform
100+ staff years
of developing silicon + device IP
Pioneered
CPO/SiPh optimized for HVM
40+ years
in analog and mixed-signal ICs for high-speed comms
40+ years
in laser packaging and SiPh optical I/O
Extensive
device library enabling Tb/mm², pJ/bit, $/Gb targets
Scale-Up & Scale-Out
Two architectures…one supplier.
Scale-Up
Ultra high-performance, scalable to over 100x of current GPU direct connect limits with minimal latency
Built for high-volume manufacturing with tightly integrated optics
Highly customizable to meet hyperscaler customers’ specific needs and future roadmap requirements
Scale-Out
1000x better bit error rate reduces re-transmits and maximizes system throughput + reliability
High degree of robotic automation in production and test reduces costs and increases output
Multiple innovations in high-volume manufacturing test and calibration raise yields
The leadership
to make it happen
Our founding and leadership team brings deep photonics and networking industry experience from Cisco, Juniper, Meta, Lumentum and Coherent.
Photonics are the answer for scaling AI infrastructure going forward. While traditional scale out designs still have a lot of growth left, there is a massive opportunity to build native GPU-to-GPU scale up architectures. Our goal at Lumilens is to be the leader in both.

Ankur Singla
CEO & founder
AI and its required infrastructure continues to grow faster than the photonics industry can deliver solutions for it. That’s why we founded Lumilens – to participate in that growth, while designing new ways to better connect and scale AI natively.
Samuel Liu
VP Products & founder
Since our founding days, Lumilens has approached innovation in photonics at a very global level. Our India/APAC teams play a key role in delivering round-the-clock innovation and highly efficient manufacturing and operations.
Ritesh Kapahi
VP/GM India & founder
You must approach innovation in photonics from a system-level perspective, not a component-level one. That’s why we’ve built Lumilens with deeply experienced team members from across the board of leading networking and optical vendors.
Dave Friedman
VP Operations & founder
The industry need is clear…how to scale AI infrastructure to meet the pace of this massive technology revolution. And the answer is also clear…photonics to scale and reinvent ultra high-speed connectivity across GPUs.
Ted Schmidt
CTO & Founder
Photonics vendors have grown the market, but haven’t fully leveraged the actual AI that their connectivity enables. Lumilens is designing its full-stack manufacturing from the ground up, using robotics and AI to the fullest extent.
Weich Fang
VP Manufacturing & Ops
Our in-house silicon innovation enables higher-density integration and more efficient fiber utilization, forming a unique foundation for both scale up and scale out architectures in modern AI data centers.
Harish Devanagondi
VP Engineering, Silicon
I’ve been at many innovative networking companies, from the early days of LANs, the Internet boom, and the start of cloud computing. The role of photonics in scaling AI is as big, or bigger than, any of these. And Lumilens will be at the heart of that.
