In this dissertation, we study two applications of wavelength division multiplexing (WDM) in optical transmission and photonic switching, and one application of Brillouin scattering in fiber sensing. The content about WDM applications includes the investigation of fiber nonlinearity in WDM systems, the utilization of different fiber media and modulation formats to reduce crosstalk due to fiber nonlinearity in WDM networks, the investigation of wavelength allocation in WDM transmission, the study of the self-injection-feedback configuration of fiber Bragg grating (FBG) based fiber laser as WDM light sources, and the dispersion compensating technique to reduce XPM-induced crosstalk in WDM transmission. The content related to photonic switching includes the FBG-based configurations of optical-cross-connects (OXC’s), the optical label swapping, the fast wavelength-tunable laser with external injection seeding, and the optical supervising technique for OXC. In fiber sensing part, the optical-time-domain reflectometry (OTDR) technique for branched and HFC networks, the Brillouin-OTDR for fiber stimulated Brillouin scattering threshold measurement, separation of distributed strain and temperature for Brillouin-OTDR measurement, and spectrum decomposing technique of Brillouin-OTDR for spatial resolution improvement have been presented and realized. These investigations and demonstrations will be useful in the fields of optical transmission, photonic switching and fiber sensing.
