Organic devices and links offer considerable potential for data communication by virtue of their ability to transmit, modulate and detect light in an architecture that is low cost, flexible, lightweight and robust. Here we have discussed an all organic optical communication system comprising of organic optoelectronic devices such as organic light-emitting diodes, organic photodiodes etc. for data communication. A polymeric (organic) optical fiber (POF) is used as transmission line connecting an organic light emitting diode and organic photodiode working as transmitter & detector respectively. A quasi solid state Dye Sensitized photo diode has been used as optical signal detector. Device characteristics including emission spectra, I-V-curves and the dynamic behavior for various optical components as used in this communication system have been recorded and analyzed. Such designed all organic optical communication system may be used for data communication in a local area communication network.
