Abstract


Polymer material is very promising in fabricating integration optical waveguide devices. Polymer waveguide devices are potential project in the field of optical communication and interconnection. Optical polymers waveguide are a research hot topic and particularly attractive in integrated optical waveguide devices because they offer easy integration, rapid processibility and low cost. This dissertation is concentrated on lucubrate the passive polymer waveguide devices, including numerical simulation , material characteristic, fabrication, application.It is necessary that simulation and analysis tools simulate, design, and optimize optical devices effectively and flexibly. Beam Propagation method (BPM) is practicable waveguide simulation method tools. They can calculate guidewave mode and radiation mode together. Aiming at the structure and refractive-index profile of waveguide, the waveguide optical field distribution has been calculated by the Generalized Douglas (GD) scheme. Compared with standard Crank-Nicholson(CN)scheme in the same computational time and resource, the method has two characteristics: small truncation error of in the transverse direction and high accuracy. It is a useful tool for designing optical waveguide devices. Crossing waveguide normalized output optical power versus intersection angle in the main waveguide and power coupling versus intersection angle are analyzed by the method. Numerical result would lay an foundation for our experiment.The fabrication of the polymer waveguide is studied experimentally. The theory of ultraviolet(UV) radiation and the experimental setup are analyzed. The physical properties of a ridge waveguide sample, such as absorbance spectra, refractive index, and thickness, are measured and analyzed. Some application of the polymer waveguide are investigated. Finally, the experiment setup of optical power measurement for polymeric waveguide film is design. The measure setup show offer convenience for future development of polymer waveguide.
