Organic electroluminescent diode (OELD) has been investigated for use as a light source of polymeric optical integrated devices. The OLED was fabricated by organic molecular beam deposition (OMBD) technique. The OLEDs were fabricated on both glass and polymeric substrates. The device fabricated on a polymeric substrate shows similar device characteristics to those on a glass substrate. Optical signals of faster than 100 MHz has been created by applying pulsed voltages directly to the rubrene doped OLED. Optical photo detectors (OPDs) utilizing superlattice structure phthalocyanines provide increased pulse response with input optical signals and the response was faster than 1 MHz.
