| Summary: | 碩士 === 國立臺灣師範大學 === 光電科技研究所 === 93 === In this thesis, we design optical pickup head system by MMI-based PBG waveguide optical splitter with a square-lattice photonic crystal and Mach-Zehnder structure with a hexagonal-lattice photonic crystal building on SOI wafer. MMI-based PBG waveguide optical splitter with a square-lattice photonic crystal is based on self-image phenomenon. We design the device according to the self-image phenomenon in MMI optical splitter based on SOI rib waveguide. We use the technique of photonic bandgap and line defect to control the direction of the light wave propagation in a waveguide. Besides, Mach-Zehnder structure with a hexagonal-lattice photonic crystal is also used to design as an interferometer.
