碩士 === 國立中興大學 === 物理學系所 === 101 === In this study the multi-functional optical waveguide devices are implemented by using the Maxwell’s fish-eye lens and geometry flattened. Applying the concept of coordinate transformation and spherical gradient index profile, the Maxwell’s fish eye lens originally with only single focusing function is flattened to form a multi-functional devices having beam shifter and focusing lens simultaneously. By adjusting material parameters and geometry structures of the Maxwell’s fish eye lens, we improve successfully the working range and the performances of the devices. First, we discuss the efficiency and the working range along the horizontal and vertical directions. Subsequently, we analyze the effect that the device works in various materials. Finally, we combine the two functions into a multi-functional optical waveguide devices and analyze the influence resulted from the combination of the two functions. Through integrating the multi-functional device into a single structure, we reduce efficiently the device size and offer a solution method for future integrated optical components.
