碩士 === 國立臺北科技大學 === 光電工程系研究所 === 99 === In this study, optical birefringence of bideposited symmetric nanorod arrays is investigated. A Ta2O5 nanorod array with zigzag structures is fabricated by serial bideposition technique. Each nanorod is composed of several unit sections and each section is composed of symmetrical subsections. From the lateral view, the sectional layer is composed of symmetrical layers ABA. The deposition plane of A is perpendicular to that of B. The equivalent refractive index and phase retardation of multiple units are analyzed and measured using ellipsometry. The result indicates that a bideposited symmetric nanorod array is potentially applied as a waveplate.
