QD Laser scales quantum dot laser production for silicon photonics and photoelectric fusion
Tuesday, February 3, 2026 at 08:17 PM
QD Laser is expanding its production of quantum dot lasers, a critical component for silicon photonics and photoelectric fusion. The company is one of only two manufacturers globally capable of producing these lasers, which are essential for high-speed, low-power data transmission in AI infrastructure.
Context
QD Laser is accelerating the mass production of quantum dot lasers, a critical component for next-generation photoelectric fusion and silicon photonics. As one of only two companies globally capable of commercial-scale production—the other being Germany's Innolume—the firm is positioning itself as a vital supplier for AI-driven data centers. These specialized lasers operate stably at temperatures up to 125°C and require no optical isolators, enabling the high-speed, low-power optical I/O necessary to overcome current copper wiring bottlenecks.
The company is scaling rapidly to meet demand for optical interconnects, targeting an annual production volume of 1 million units by 2026. This push follows the successful deployment of 60,000 units for IOCore chips, which support data rates between 100-500 Gbps. With the broader semiconductor industry shifting toward light-based chip architectures, QD Laser expects this volume ramp-up to drive its transition to full-year profitability by March 2027.
