Riber receives new order from QD Laser
French MBE firm Riber has announced an order for an MBE 6000 production system from QD Laser, a leading Japanese player in quantum-dot laser technology.
The system will be optimised for the epitaxial synthesis of GaAs-based quantum dots tailored for optical datacom, a high-growth sector propelled by exponential data expansion and the rapid integration of AI across global networks.
For Riber, this order represents, within the space of one month, the third MBE 6000 project 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. According to Riber, the MBE 6000 system meets these requirements through the combination of an optimised 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 QD Laser was among the first companies to qualify Riber’s ABI 1000 cell, recognised 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.
The MBE 6000 system is scheduled for shipment in 2026.
