Buried Metal Grating for Vertical Fiber-Waveguide Coupling with High Directionality
碩士 === 國立交通大學 === 光電工程學系 === 101 === Coupling efficiency of the grating coupler which vertically couples fiber-waveguide is affected by directionality and fiber mode overlap. Although the directionality can be improved by poly-silicon overlay grating structure or additional bottom mirror, these stru...
