Abstract
Conjugated polymer light-emitting diodes (PLEDs) was considered as the next generation's display technology; Moreover it may find more technological applications. In this thesis, we try to fabricate an OEIC integrating PLED with SU-8 waveguide on silicon substrate. It can be used for chip-to-chip data communication in future. We utilize PLED as the light source and SU-8 as waveguide. Top emission of PLED has the maximum luminescence intensity. For this reason, we have to make PLED above waveguide and couple light into the waveguide. After many approaches, we found a workable method by doping SiO2 particles in SU-8 as a diffuser sheet. The incident light reach the diffuser sheet and undergo a large angle scattering. And a fair amount of light is directed into the waveguide. We believe our device structure can be further improved and become pratical in future.
