A Review of Semiconductor-Based Monolithic Optical Phased Array Architectures
Hossein Hashemi
Abstract
Semiconductor-based monolithic optical phased arrays (OPA) enable optical beam-steering for lidar and 3D imaging, free-space optical communications, projection and 3D holographical displays, and neural probes among many other possible applications. This paper provides a review of OPA operating principles, architectures, key building blocks, and remaining research challenges.
