There is a growing interest in the research and development of optical wireless communication (OWC) systems, including free-space optical communications (FSO), visible light communications (VLC), and underwater wireless optical communications (UWOC). This is mainly due to significant advancements in optical sources from high-performance light-emitting diodes (LED), solid-state laser diodes (LD), and high-speed photodiodes (PD) in different optical spectra (i.e., infrared, visible, ultraviolet). Exploring these new optical spectra for the purpose of wireless communication is a big interdisciplinary research challenge. Additionally, due to the storage of traditional radiofrequency (RF) communication spectra, using optical spectra for wireless communication can also release the heavy burden of RF wireless communication. OWC technologies, such as optical camera communication (OCC) and image sensor-based Internet of Things (IoT), visible light positioning (VLP) has received much attention recently. Light fidelity (LiFi), as a special form of OWC, is emerging to provide a high-speed wireless link, supporting multiuser and bidirectional access. It may also be integrated into the future 6G mobile networks.

This workshop aims to bring together the research accomplishments provided by leading researchers from academia and the industrial experts. To further promote the development of these areas, we invite researchers to contribute original research manuscripts as well as review articles on recent advances in the design and performance analysis of innovative systems that employ the concepts of wireless communication and networking. Articles dedicated to the integration of these concepts with emerging Intelligent Reflecting Surfaces (IRS) or UAVs are highly preferred.
