#Press Release @Photonics West’21

Taking a critical step toward developing LiDAR systems for widespread commercial applications, CEA-Leti, in the frame of Nanoelec/Photonics Sensors program, has developed genetic algorithms to calibrate high-channel-count optical phased arrays (OPAs), as well as an advanced measurement setup enabling wafer-scale OPA characterization. OPAs are an emerging technology made of arrays of closely spaced (around 1µm) optical antennas and which radiate coherent light in a broad angular range. Results reported by CEA-Leti at Photonics West 2021.
