Abstract
Organic electroluminescent diode (OELD) has been investigated for use as a light source of polymeric optical integrated devices for use as an optical interconnects in data communication systems. Several kind of OLED has been investigated for a light source of optical integrated device. The OELDs consist of indium-tin-oxide (ITO) coated substrates, hole-transporting layer of α-NPD (4,4'-bis[N-(naphthyl)-N-phenyl-amino]-biphenyl), an emissive layer and silver containing magnesium cathode. The OLED was fabricated by organic molecular beam deposition (OMBD) technique. As an emissive layer, rubrene (5,6,11,12-tetraphenylnaphthacene) doped Alq3 (8-hydroxyquinoline aluminum), with an emission peak center at 560 nm, was employed. Optical pulses of faster than 100 Mb/s have been generated from the OELD. The OLEDs were fabricated on a glass substrate and a polymeric substrate. The device fabricated on a polymeric substrate shows similar device characteristics to that on a glass substrate. Emission characteristics and the pulse response characteristics of the OLED as regards it use as a light source for the polymeric waveguide have been discussed.
