| Summary: | 碩士 === 國立高雄科技大學 === 電子工程系 === 107 === In this thesis, the property of silicon-based plasmonic component is discussed. We use a variety of cavities to design the wavelength division multiplexing devices.
First, we use triangle cavity to design the silicon-based plasmonic wavelength division multiplexing devices. By properly adjusting the height of the triangular cavity, we can explore the characteristics of the structure, generate the sensitivity of the tip and filter out some wavelength of futility. Then the wavelength is utilized in the optical communication band and the efficiency is about 55%, 55% respectively. For example, 1290nm or 1310nm optical communication band. Finally, designing the wavelength division multiplexing devices, which contain these two communication bands.
Second, we use a rectangle cavity to design the silicon-based plasmonic wavelength division multiplexing devices. By properly adjusting the height of the rectangle cavity, we can explore the characteristics of the structure, generate the phenomenon of the Bragg grating and filter out some wavelength of futility. The wavelength is utilized in the optical communication band and the efficiency is about 55%, 55% respectively. For example, 1290nm or 1310nm optical communication band. Finally, designing the wavelength division multiplexing devices, which contain these two communication bands.
In the end, we use a ring cavity to design the silicon-based plasmonic wavelength division multiplexing devices. By properly adjusting the radius of the ring cavity, we can explore the characteristics of the structure, generate the phenomenon of the electromagnetically induced transparency (EIT) and filter out some wavelength of futility. The wavelength is utilized in the optical communication band and the efficiency is about 55%, 55% respectively. For example, 1290nm or 1310nm optical communication band. Finally, designing the wavelength division multiplexing devices, which contain these two communication bands.
