Optical Phased Arrays for LiDAR

Taking a step nearer developing LiDAR systems for widespread commercial applications, CEA-Leti 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 ...
