Abstract
Optical wireless communication (OWC) is an emerging area where research and development are growing worldwide. The radio-frequency (RF) spectral resource in traditional communication band has been exhausted, and frequency allocation will be a big issue, particularly for the future 6G networks. The non-terrestrial-networks (NTN) in 6G introduce new applications, such as automatic logistics with drones, satellite communication, underwater communication, etc, making OWC inevitable for such ultra-broadband and secure wireless transmissions. This tutorial covers the recent advances and future perspectives in OWC, free-space-optical (FSO) communication and sensing, from devices to applications.
