Beyond 100 Gb/s: Advanced DSP techniques enabling high spectral efficiency and flexible optical communications

Coherent optical communications leveraged the fundamental philosophies and building blocks of mature wireless/copper-wire DSP technologies and has been a huge success with polarization-multiplexed QPSK at 100Gb/s per channel transponders currently in wide deployments. We discuss on further advances in DSP techniques to enable single-carrier transmission approaching 1 Tb/s as well as software-defined flexible transponders supporting adaptive modulation formats and elastic optical networks.Department of Electrical EngineeringDepartment of Electronic and Information EngineeringRefereed conference pape

Characteristics of supercontinuum generation under the influence of a weak continuous-wave trigger

Oral - MF3We numerically study the impacts of introducing a minute continuous-wave trigger on the properties of picosecond supercontinuum generation; namely the bandwidth, temporal coherence and pulse-to-pulse stability. © 2011 IEEE.published_or_final_versionThe 24th Annual Meeting of the IEEE Photonics Society (PHO 2011), Arlington, VA., 9-13 October 2011.
