    We developed a fast-switching optical phased array (OPA) for agile optical wireless communication. This technology enables rapid beam steering for multiple users and tracking moving objects, enhancing network flexibility.

    Area of Science:

    • Optical wireless communication
    • Photonics
    • Wireless networks

    Background:

    • Mechanical beam steering in optical wireless systems is too slow for dynamic user needs.
    • Limitations include slow switching between users and difficulty tracking moving targets.

    Purpose of the Study:

    • To demonstrate a fast-beam-switching optical phased array (OPA) for agile wireless communication networks.
    • To enable rapid beam reconfiguration for point-to-multi-point (P2MP) scenarios and tracking moving objects.

    Main Methods:

    • Developed an OPA system for fast beam switching between two receivers in a P2MP setup.
    • Utilized a loss-free image transmission experiment to validate switching stability.
    • Created an approach for the OPA to track moving object trajectories.
