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.
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.
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".
Optically pumped germanium-tin micro-disks encapsulated by silicon nitride and transferred onto aluminum pillars generate a 2.5-micron laser beam with an ultra-low threshold. Laser beams with no III-V materials are no longer a dream… See results published in Nature Photonics.
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.
