CEA-Leti presenting at Photonics West, including Invited Paper on optical phased arrays for LiDAR
At Photonics West 2025 in the Moscone Center, San Francisco (25–30 January), micro/nanotechnology R&D center CEA-Leti of Grenoble, France is presenting six papers (including an invited paper) detailing its recent breakthroughs and results for photonics-based applications. Topics to be covered include:
- silicon photonics for computing, AI, communication & quantum technologies;
- integrated solutions for biosensing with integrated mid-infrared laser sources;
- integrated frequency-modulated continuous-wave LIDARs based on flash illumination, or optical phased-array beam steering.
In addition, CEA-Leti's booth #5129 (North Hall) in the Moscone Center French Pavilion is exhibiting silicon photonics components, QCL-based optical sensors, and micro-LEDs for displays, and optical communications.
