Summary: | 博士 === 國立交通大學 === 光電工程系所 === 95 === This dissertation investigates the applications of microwave photonics and optoelectronics package in last-mile multi-service access networks offering video, voice, and data to customers simultaneously. For the content about microwave photonics applications, the impact of both the Mach-Zehnder modulator (MZM) nonlinearity and the imperfect MZM with finite extinction ratios on millimeter-wave signals (mm-wave) will be theoretically analyzed and experimentally investigated. Optimal conditions for RF signal generations using imperfect MZMs based on double-sideband with optical carrier suppression (DSBCS) modulation are also discussed. Based on the optimal condition, the optical-wireless network offering both wireless and wired-line access approaches and the hybrid access network integrating radio over fiber (RoF) and fiber-to-the-home (FTTH) systems are proposed and investigated. For the content related to applications of optoelectronics packages for bidirectional or triple-directional FTTH systems providing triple-play services, power metallurgy (PM) is proposed as a cost-effective method of fabricating metal parts for optoelectronic modules. The weldability of PM stainless steel is investigated, including welding defect mechanism, post-welding-shift, tracking error, and reliability test. These investigations and demonstrations will be useful in the future optical multi-service access networks.
