In this dissertation, we investigate the designs and applications of fiber Bragg grating-based optical add-drop/cross-connect multiplexing systems for WDM long-distance trunk and ring networks, multiple AM-VSB signals transmission systems, and wideband optical amplifiers in metropolitan area network. In fiber Bragg grating-based optical add-drop/cross-connect multiplexing systems, the utilization of multi-port circulator and fiber Bragg gratings can hugely reduce the crosstalk and compact the configurations. Furthermore, we propose the utilization of Mach-Zehnder fiber Bragg grating-based devices with the associated mechanical Optical switches to construct large-dimension fixed and reconfigurable optical add-drop/cross-connect multiplexing system without the needs of additional WDM multiplexers and demultiplexers.
In multiple AM-VSB signals transmission systems, we demonstrate the transmission of AM-VSB CATV video signal at 1.55-mm and 155-Mb/s data signal at 1.3-mm over a multi-mode fiber local area network (MMF-LAN) link. On the other hand, we not only demonstrate the possibility of optical circulator with optical bandpass filter, and MUX/DEMUX configurations, but also discuss the transmission distance of extension and the elimination of crosstalk for bi-directional transmission systems of multiple AM-VSB CATV signals. The system demonstration confirms the feasibility of multiple AM-VSB signals over the existing MMF-LAN and bi-directional transmission systems.
For the application of wideband optical amplifiers in metropolitan area network, we also present erbium-doped fiber amplifier (EDFA) for hybrid WDM systems, and the dispersion-compensated gain-clamped 90 nm wideband optical amplifier in 10 Gb/s DWDM transmission systems. These designs, demonstrations, and results will be useful for WDM long-distance trunk and ring networks applications.
