CEA-Leti's silicon photonics platform allows miniaturization, power efficiency, cost reduction and scalability of photonic integrated circuits (PIC). Pioneering silicon photonics for 20 years, CEA-Leti has designed a technology toolbox featuring state-of-the-art performance for communication, computing and sensing.
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).
CEA-Irig was among the partners on a French national research agency (ANR) project that resulted in the on-demand emission of single photons in silicon at 1.28 µm, a wavelength used in telecommunications. They did it by introducing carefully-engineered defects into the material. The goal is to integrate this photon source into CEA-Leti chips for quantum communications.
A silicon qubit tester recently acquired by CEA-Leti will substantially speed up quantum computer research. The tester can measure the electrical performance of several hundred qubits processed on a 300 mm wafer at 1.7 K (-271.3 °C). The qubits that make it through these tests will then be tested individually on a cryostat at Institut Néel at temperatures below 100 mK, a requirement for integration into quantum processors.
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.
