The use of organic optoelectronic devices such as organic light-emitting diodes and organic photodiodes in micro-optical systems is discussed. Potential applications like optical interconnects and optical sensor systems are examined. Device characteristics including emission spectra, I-V-curves and the dynamic behaviour are analyzed. In the combination with a polymeric optical fibre (POF) a transmission line comprising a organic light emitting diode and organic photodiodes is demonstrated. An important step towards integration is realized by coupling the amplified spontaneous emission of an organic semiconductor material into a single mode polymethylmethacrylate (PMMA) waveguide.
