In recent years, organic small molecule and polymer light-emitting diodes (LEDs) and photodetectors (PDs) have been used as optoelectronic components in visible light communications (VLC). The first study appeared in  which demonstrated that data transmission rates in the hundreds of kb/s region are possible. This was further improved by using advanced modulation formats such as orthogonal frequency division multiplexing (OFDM) . Ethernet transmission speeds were reported for the first time in  and were achieved using the multilayer perceptron artificial neural network equalization technique. The current state-of-the-art transmission speeds available in organic VLC (OVLC) transmission is 55 Mb/s using aggregated wavelength multiplexed data streams . This chapter gives an overview of organic-based VLC focusing on the LED technology trends, organic LED (OLED)-based devices, the organic semiconductors, and visible light PDs. To enhance the OLED-based VLC links blue filtering and a number of equalization schemes including artificial neural network equalizer, decision feedback equalizer, and linear equalizer are discussed and their performance are compared and contrasted. Finally an experimental all-organic VLC system employing both OLED and organic PDs employing artificial neural network base equalizer is introduced and its performance is evaluated. The chapter is completed with concluding remarks.
