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.
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-Leti today announced that it has collaborated with Siemens Digital Industries Software to offer an updated process design kit (PDK) that enables photonic designers to select multiple methodologies, including layout centric, schematic driven and layout automation and provides access to CEA-Leti’s 300mm photonics multi-project wafers (MPW).
GRENOBLE, France – March 18, 2021 – CEA-Leti scientists have developed a lensless, infrared spectral-imaging system for medical diagnostics. The first application is cancer detection in the tissue section and the second is the identification and discrimination of microorganisms, such as bacteria. Presented in two papers at the Photonics West 2021 Digital Forum, the label-free technology also could eliminate sample preparation in a reliable and user-friendly device that may foretoken automation of some diagnostics.
GRENOBLE, France – March 2, 2021 – CEA-Leti, a technology research institute of CEA Tech, will present 14 papers during Photonics West 2021, March 6-11, including an invited paper, "Advanced roughness characterization for 300mm Si photonics patterning & optimization".
Aledia, a French startup pioneering a disruptive technology for microLED displays, today announced it has manufactured the world's first microLED chips produced on 300mm (12") silicon wafers. The company, which developed its breakthrough technology on 200mm (8") silicon wafers over the past eight years, will produce the chips on both 200mm and 300mm wafers.
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.
