Integrated optical phased arrays : augmented reality, LiDAR, and beyond

Integrated optical phased arrays, fabricated in advanced silicon-photonics platforms, enable manipulation and dynamic control of free-space light in a compact form factor, at low costs, and in a non-mechanical way. As such, integrated optical phased arrays have emerged as a promising technology for many wide-reaching applications, including LiDAR sensors and augmented-reality displays. In this thesis, novel integrated-optical-phased-array devices, systems, results, and applications are presented. First, beam-steering optical phased arrays for LiDAR are shown, including the first beam-steering optical phased arrays powered by monolithically-integrated on-chip rare-earth-doped lasers, the first beam-steering optical phased arrays controlled using heterogeneously-integrated CMOS driving electronics, and the first single-chip coherent LiDAR with integrated optical phased arrays and CMOS receiver electronics.
