Abstract
Facing escalating demands for high-speed, large-bandwidth, and low-latency wireless data links, laser communication technology has emerged as a promising technology.While free-space optical communication conventionally utilizes nearinfrared light sources, there has been growing interest in exploring new spectral resources, including visible lasers.Recently, laser-based white light has been demonstrated in visible light communication (VLC), with a unique capability to seamlessly integrate with illumination and display systems.This review summarizes the key devices and system technologies in semiconductor-laser-based white light for VLC-related applications.The recent advances and many emerging applications in the evolution of lighting, display, and communication are discussed.
