ultrahigh-speed optical communication temporal signal processor
2011/5/15
An all-optical polarization temporal signal processor is demonstrated, which performs well in 40-Gbits/s optical signal differentiation with error of ~0.1 and efficiency of ~12%, 80-GHz 3.3-ps optical...
Polarization-Dependent Loss Induced Penalties in PDM-QPSK Coherent Optical Communication Systems
Fiber optics communications Coherent communications Polarization
2010/6/10
We evaluate PDL-induced penalties in PDM-QPSK coherent systems with both lumped model and distributed model. We find the lumped model significantly over-estimates PDL penalties and PDM coherent system...
