KISTA, Sweden and FREMONT, CA, Mar 25, 2026 – Sivers Semiconductors has partnered with O-Net Technologies and Enablence Technologies to develop an external light source (ELS) module for Co-Packaged Optics (CPO) in AI data centers and high-performance computing (HPC) systems. O-Net will serve as the ODM partner, integrating Sivers laser arrays with Enablence’s NxN Star Coupler to build a scalable module for scale-out and scale-up optical systems.
CPO integrates optical elements into GPU and switch packages, reducing energy use by about 80% compared to copper. An IDTechEx report from December 2025 projects the CPO market will exceed $20 billion by 2036, with a CAGR of 37% from 2026 to 2036. External light source solutions are expected to account for about 10% of the market.
“ELS is a crucial companion to CPO because it separates temperature-sensitive lasers from the extreme heat of high-power processors, ensuring wavelength stability and significantly enhancing system reliability and serviceability,” said Alex McCann, managing director for Sivers’ photonics business. “Our high-performance DFB laser arrays deliver the reliability and wavelength stability required to accelerate the deployment of AI datacenters with CPO based architectures.”
“O-Net Technologies is pleased to partner with Sivers and Enablence to enhance our advanced external light source module,” said Austin Na, CEO and chairman of O-Net Technologies. “Together, we’re enabling a practical, scalable ELS aligned with the needs of High-Performance Compute (HPC) and AI data centers.”
“We are excited to partner with Sivers and O-Net to help redefine how optical interconnects scale for the AI era,” said Todd Haugen, CEO of Enablence Technologies. “Our NxN Star Coupler enables efficient wavelength distribution at scale, and together we are unlocking an effective optical pathway for CPO based architectures to keep pace with exponential growth in AI data center compute.”
