Our research is focused on three aspects of advanced optical fiber communication systems dynamic wavelength division multiplexing WDM networks, line width in sensitive coherent optical analog links, and impact of fiber nonlinearities on optical communication systems. During the reporting period, we have been working in all three fields, as follows. In the area of WDM networks, we investigated, designed, and are currently implementing an experimental coherent WDM optical network with a throughput of 3 Gbsnode. In the study of coherent optical analog links, we analyzed two linewidth-insensitive schemes that could overcome the impact of phase noise of semiconductor laser diodes. In the area of fiber nonlinearities, we evaluated the performance of optical WDM systems in the presence of four-wave mixing, and are analyzing the impact of stimulated Brillouin scattering on such systems. In addition, we have experimentally observed fiber-induced parasitic phase modulation, investigated its properties, and are beginning to investigate its impact on optical communication systems.
