Abstract
The Optical Phase Arrays (OPA) have a high potential for a new generation of LiDAR (Light Detection and Ranging) systems since they avoid mechanical beam scanning. During the development of such LiDAR, many characterizations are essential to optimize its components and get a full control of its performance.
In this paper, we present a dedicated setup for 1D-OPA characterization @1550 nm. Its versatility and performance are illustrated with the first results concerning the beam forming efficiency and the lag time for beam direction change of a 256 channels OPA.
Presenter
CEA-LETI (France)
J. Hue received his PhD from Grenoble University in 1993 (Behaviour of mirrors under high continuous power of CO2 laser). He has been working at CEA since 1990. Firstly, in the Optronic Department at CEA-LETI, he has been involved during 10 years in laser damage threshold especially for the Nation Ignition Facility and the Megajoule projects. He stayed during 2 years at LLNL (Lawrence Livermore National Laboratory). One of his major contribution is the development of the first automatic laser damage test benches. Then, he worked during 5 years to reduce and characterize the nanodefects on the EUV blanks (application to EUV Lithography). Then in 2006, he joined the Micro Technology Department for the Health and Biology, where he was involved in European programs as project and technical leader. He contributes to optical biological detection for French start-ups : Aryballe Avalun,..., In 2019, he joined the Optronic Department, in charge of optical component tests for LiDAR detection.
