Facing the major application needs of national security and national economy, aiming at the research field of phased array optics, we focus on key technology research and system engineering innovation such as optical phased array chip, optical phased array laser detection and communication, and explore the application basic research on spatio-temporal dimension control of phased array optics, and strive to become a well-known scientific research institution engaged in phased array optics research and advanced research personnel training base in China.

Research Direction

Phased array optics mainly studies the scientific and technical problems of "how to dynamically control the time (phase) and space (geometric arrangement) characteristics of the light wave radiation array unit to achieve arbitrary control of the target light field".

1.Design and manufacture of 3D optical phased array chip;

2.Research and development of optical phased array Lidar and application of autonomous driving;

3.Development of optical phased array laser communication system and application of satellite Internet.
