A Gain-Enhanced Silicon-Photonic Optical Phased Array with Integrated O-Band Amplifiers for 40-m Ranging and 3D Scan

For the first time, we demonstrate 40-m range detection and 3D depth scan up to 20 m using a silicon-photonic optical phased array with integrated amplifiers, promising a high-performance solid-state light-detection and ranging (LiDAR) system.
