In this dissertation, we study the applications of fiber laser in communication systems and sensor networks. The content about communication system applications includes a wavelength-tunable linear-cavity pulse laser, an actively mode-locked fiber ring laser, and a wavelength-tunable light source using an erbium-doped fiber amplifier and a Fabry-Perot laser diode. The content related to sensor network applications includes a sensor network with self-healing functions, a hybrid star-ring architecture and a star-bus-ring architecture for sensor networks, an intensity and wavelength division multiplexing sensor system, a long-distance sensor system using a Raman amplifier, and a remote sensor system using an erbium-doped waveguide amplifier and a semiconductor optical amplifier. These investigations and demonstrations will be useful in the fields of communication systems and sensor networks.
