What Lumilens does

Lumilens is a private, venture-backed company founded in 2024 that designs and manufactures silicon photonics-based photonic interconnects for AI data center infrastructure, headquartered in San Jose, California, with operations in the United States and India/APAC. Its products are aimed at AI hyperscalers and large AI infrastructure operators that need to scale GPU clusters beyond the limits of copper and basic photonic transceivers, addressing bandwidth, thermal, and power constraints driven by exploding LLM and training cluster sizes. The company employs between 11 and 50 staff, including a leadership team drawn from Cisco, Juniper, Meta, Lumentum, and Coherent.

Lumilens' core product is a unified photonic interconnects platform that spans high-density pluggable, near-packaged, and co-packaged optics, positioned to support both scale-out (standards-aligned, cluster-to-cluster) and scale-up (ultra high-performance, direct GPU-to-GPU) architectures. The company claims its in-house silicon photonics and scale-up architecture can support 100x higher GPU-to-GPU direct connection density than existing solutions, enabling massive pod scaling and GPU disaggregation. Manufacturing is built around end-to-end automation with customized robotics and AI-optimized processes for die attach, wire bond, and active alignment, intended to deliver higher yield, product quality, supply chain continuity, and the ability to 'manufacture anywhere' through an open ecosystem.

The business model is B2B enterprise sales, with direct engagement of AI hyperscalers and infrastructure providers through a relationship-driven, technical-collaboration motion. Commercial vehicles include hardware product sales and joint development agreements; the most material disclosed commercial relationship is a May 2026 strategic joint development and supply agreement with POET Technologies, under which Lumilens placed a $50M initial purchase order for EOI-based optical engines targeting 800G and 1.6T pluggable transceivers, with a stated potential to scale to $500M+ in cumulative purchases over five years. The company has raised approximately $39M across two disclosed funding rounds (May 2024 $30M led by Mayfield; May 2025 $9.2M led by Accton Technology), is hiring into manufacturing, silicon photonics, and commercial functions, and is not yet generating commercial product revenue, with engineering samples expected late 2026 and hyperscaler production ramp targeted for 2027.

Core offering

Lumilens designs, manufactures, and sells photonic interconnect hardware — high-density pluggable, near-packaged, and co-packaged optics — for AI data center infrastructure. The products enable both scale-out (cluster-to-cluster) and scale-up (direct GPU-to-GPU) architectures, and are built on the company's proprietary in-house silicon photonics platform with AI-optimized automated manufacturing.

Product overview

Lumilens provides a unified photonic interconnects platform for massively scaling AI compute infrastructure. The company's primary offering combines photonic interconnects with next-generation manufacturing capabilities, supporting both scale-out (high-density pluggable optics aligned with industry standards) and scale-up (ultra high-performance co-packaged optics for GPU-to-GPU direct connections up to 100x current limits) architectures. The platform is built on in-house developed silicon photonics and enhanced by highly automated manufacturing using robotics and AI-optimized processes.

• POET TechnologiesflagshipStrategic or Co-development Partner · 14 May 2026POET Technologies and Lumilens entered into a strategic joint development and supply agreement on May 14, 2026 to advance wafer-level photonic integration for AI infrastructure using a new Electrical-Optical Interposer (EOI) platform. Lumilens placed an initial $50 million purchase order with POET for EOI-based optical engines targeting 800G and 1.6T pluggable transceivers. The collaboration has potential to scale to over $500 million in cumulative purchases over five years. Engineering samples are expected in late 2026 with production ramp aligned to hyperscaler customer deployments in 2027. The agreement includes a warrant grant to Lumilens for up to 22.9 million POET common shares at $8.25 per share over nine years.
