Our research is focused on four aspects of advanced optical fiber communication systems dynamic wavelength division multiplexing WDM networks, linewidth insensitive coherent optical analog links, video distribution systems using direct frequency modulation of semiconductor laser, and impact of fiber nonlinearities on optical communication systems. In the area of WDM networks, we investigated, designed, and are currently implementing a coherent optical network with a total throughput of 12 Gbits. 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 video distribution systems, we investigated the performance of novel systems using direct frequency modulation of semiconductor lasers for subcarrier-multiplexed video distribution. 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 networks.
