| With the development of optical communication, optical splitter is one of the key component in communication system, optical network terminal, passive optical network, CATV system and optical local area network. The main function of optical splitter is used as optical signal splitter/combiner. In this dessertation, we conducted research on design of high-performance small-size optical splitters and fabrication of low-loss buried splitters based on ion-exchange on glass.In this dessertation, we conducted a systematical research on the glass-based ion-exchange technology. Based on this technology, we realized the low-loss buried single-mode waveguide and 1×8/1×16/1×32 power splitters which have partially reached production standard.During the fabrication of splitters, we came up against some problems, such as metallic silver deposition, asymmetrical buried depth of waveguides and so on. And then we designed corresponding suitable experiments to solve them. It laid the ground-work of the future development of galss-based ion-exchange device which has better performance.In order to adapt to the future development of optical splitter, we proposed a design of high-performance 1×16/1×32 optical splitters of 2.5cm size. In this dessertation, we have a detailed analysis of how to design them based on ion-exchange technology on glass systematically. First, we selected FD-BPM method and global parameters according with experiment to simulate our design. Second, we tried a novelty method, which divide the design to geometrical design and performance design. Third, we discussed how to select design structure, main design parameters and how to carry out geometrical design in geometrical design segment. Forth, we analyzed performance problems and solutions of geometrical design in performance design segment. At last, we realized the design of high-performance small-size glass-based ion-exchange 1×16/1×32 optical splitters by optimizing geometrical design with performance solutions. |
