Visible Optical Fiber Communication

Abstract

This paper provides an overview of recent developments affecting in-vehicle optical networks. Visible light sources are now being used in this field, bringing advantages in both visibility and workability. In particular, current trends and subjects affecting the key devices used in these networks, such as visible light sources, optical fibers, optical circuits and transceiver modules, are explained. We consider that the use of a wavelength division multiplexing (WDM) technology is promising for realizing further advances in high-speed communications. We will briefly introduce the optical devices for WDM that have been developed in our research group.
