摘要

This tutorial focuses on devices and technologies that are part of laser-based visible light communication (VLC)systems.Laser-based VLC systems have advantages over their light-emitting-diode-based counterparts,including having high transmission speed and long transmission distance.We summarize terminologies related to laser-based solid-state lighting and VLC,and further review the advances in device design and performance.The high-speed modulation characteristics of laser diodes and superluminescent diodes and the on-chip integration of optoelectronic components in the visible color regime,such as the high-speed integrated photodetector,are introduced.The modulation technology for laser-based white light communication systems and the challenges for future development are then discussed.
