innovation for industry
Cheap, high-speed photonic components are required to cope with today’s boom in data communications, especially optical communications at Data Centers. The MASSTART project’s aim is to transform holistically the assembly and characterization of highspeed photonic transceivers, thereby drastically reducing their mass production cost. This will guarantee European leadership in the photonics industry for the next decade.

◾2D conversion layers: blue-to-green conversion layers based on InGaN/GaN Quantum Wells(30 x QW) have been grown on sapphire substrates by Novagan. Blue absorption of 1 % per QW means that light trapping architecture will be required at pixel level. Similarly, AlInGaP QW, blue-to-red conversion layers have been successfully transferred to sapphire substrates. While optical measurements on a CEA-Leti dedicated optical bench have indicated blue-to-red down conversion, the observed strong light guiding effect suggests dedicated light extraction structures to be implemented at pixel level (under investigation at CEA-Leti).
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
