Abstract

This letter presents new experimental results on a 1-Mb/s organic visible light communications system. These results are the first demonstration of a fully organic free space optical communications system. Due to low charge transport characteristics, organic devices are typically highly band limited in the hundreds of kilohertz region (up to 135 kHz in this letter). Therefore, an artificial neural network (ANN) equalizer is required to undo the effects of intersymbol interference. Without the ANN, the maximum link performance corresponds to a data rate of 350 kb/s; however, with the ANN, a transmission speed of 1.15 Mb/s could be supported.
