碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 104 === In this thesis, a novel ZnO plasmonic nanolaser with metallic gratings is proposed and analyzed with the finite element method. ZnO is chosen as the gain medium, and Al is chosen as the metal. The one-dimensional periodic grating with a defect is made of an Al film, and the ZnO nanowire is placed on it. With the appropriate design, the metallic grating can become both a high-reflectivity mirror and a good output coupler. As a result, compared with traditional nanocavities without grating, the novel nanocavity can increase both Q/Vm and light extraction efficiency, so it can generate laser beams more easily. This thesis provides a new way to design ultraviolet plasmonic nanolasers.
