Abstract:

Our research is focused on three major aspects of advanced optical fiber communication systems dynamic wavelength division multiplexing WDM networks, fiber nonlinearities, and high dynamic range coherent analog optical links. In the area of WDM networks, we have designed and implemented two high- speed interface boards and measured their throughput and latency. Furthermore, we designed and constructed an experimental PSKASK transceiver that simultaneously transmits packet-switched ASK data and circuit-switched PSK data on the same optical carrier. In the area of fiber nonlinearities, we investigated the theoretical impact of modulation frequency on cross-phase modulation XPM in dispersive fibers. In the area of high dynamic range coherent analog optical links, we developed theoretical expressions for the RF power transfer ratio or RF power gain and the noise figure NF of angle- modulated links. We then compared the RF power gains and noise figures of these links to that of an intensity modulated direct detection DD link.
