CEA-Leti is developing a new generation of photonic components: micro LED (µLED) arrays. This breakthrough technology brings advances in multiple applications including smart lighting, augmented reality in integrated smart glasses and large/transparent, flexible 3D displays.
A new generation of photonic components: µLED arrays.
MEMS and NEMS—micro- and nanoelectromechanical systems—are tiny devices like sensors, actuators, and micromirror arrays, with moving parts that are sensitive to a physical quantity like speed, pressure, or direction. They convert this physical quantity into an electrical signal, which can, in some cases, operate an integrated micro-actuator.
Scintil Photonics creates fully integrated silicon-based photonic circuits. In short, these circuits contain all the components that are required for optical communications, from lasers to modulators and photodetectors. The startup’s integrated circuits have two key advantages: they are quicker and less costly than existing solutions.
The 2021 CEA-Leti Scientific Report highlights the major inroads it has made over the past year. Industrial partners will find within the latest R&D available to drive their business value up.
With CEA-Leti’s support, LMGP, Institut Néel, and applied economics lab GAEL have been investigating the rare and critical elements (gallium, indium, yttrium, and cerium) in white LEDs.
Within CEA Tech and CEA-Leti, activities of the Optics and Photonics division cover most of the largest industrial markets for photonics:
All-wavelength imaging (Gamma and X rays, visible, infrared, THz)
Optical data communications
Optical environmental and 3D sensors
The R&D projects are carried out with both industrial and academic partners. The industrial partners of the Optics and Photonics division range from local SMEs to overseas and global companies.
Our developments merge fundamental physical aspects with advanced technological developments, they interweave nano-sciences, optics, micro-electronics, advanced nano-fabrication, integration and packaging, while taking into account system requirements.
Optics and Photonics division employs 345 persons overall, 235 permanent R&D engineers and technicians, 43 CEA experts and 45 PhD students and post docs. 74 patents filed in 2020 and 700 patents in portfolio
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.
