“…Although light emitting diodes have been traditionally used as transmitters (Txs) [2] in VLC, the demands of higher data rates in the gigabit per second range have brought laser diodes (LDs) under consideration as a potential Tx in VLC due to their much higher modulation bandwidth, beam convergence, and energy efficiency [3]. Demonstrations showed that LD-based VLC can provide illumination and communication simultaneously [4][5][6]. Although most LD-based VLC systems depend on line-of-sight transmission, in practical mobile systems, beam steering methods primarily used in free space optics can be employed.…”

We propose and experimentally demonstrate a recorded 1-m bidirectional 20.231-Gbit/s tricolor R/G/B laser diode (LD) based visible-light communication (VLC) system supporting signal remodulation. In the signal remodulation system, an LD source is not needed at the client side. The client reuses the downstream signal sent from the central office (CO) and remodulates it to produce the upstream signal. As the LD sources are located at the CO, the laser wavelength and temperature managements at the cost-sensitive client side are not needed. This is the first demonstration, to our knowledge, of a >20 Gbit∕s data rate tricolor R/G/B VLC signal transmission supporting upstream remodulation.
