QD Laser orders Riber MBE 6000 to scale quantum dot laser production for datacoms
Molecular beam epitaxy (MBE) system maker Riber S.A. of Bezons, France has received an order for an MBE 6000 production system from Japan’s QD Laser Inc, which was founded in 2006 after collaboration between Fujitsu Laboratories Ltd and the University of Tokyo and specializes in developing, manufacturing and commercializing quantum dot lasers and advanced optoelectronic devices.
Scheduled for shipment in 2026, the system will be optimized for the epitaxial synthesis of gallium arsenide (GaAs)-based quantum dots tailored for optical datacoms, a high-growth sector propelled by exponential data expansion and the rapid integration of artificial intelligence across global networks.
This latest order represents Riber’s third MBE 6000 project within a month dedicated to the production of quantum dot-based epiwafers for the datacom sector, confirming the MBE 6000 platform as a reference industrial solution for these high-value applications, in line with the increasing production-scale requirements of the datacom market.
Quantum dot growth is particularly sensitive to epitaxial growth conditions, notably temperature uniformity and deposition rate stability. The MBE 6000 system is said to meet these requirements through the combination of an optimized chamber design, advanced control software and highly reliable key components, enabling precise, stable and reproducible control of growth parameters.
QD Laser is a long-standing and strategic customer of Riber. The first production system was delivered as early as 2008, and it was among the first companies to qualify Riber’s ABI 1000 cell, recognized for its control of the stability, uniformity and reproducibility of gallium or indium deposition, while offering double the loading capacity compared with standard effusion cells.
