The potential for pulse quality enhancement of the dispersion-imbalanced fiber loop mirror (DILM) was confirmed using high-resolution coherence time analysis. Sufficient improvement of a simple single electroabsorption modulator (EAM)-based pulse source was demonstrated that would permit OTDM multiplexing to a data rate of 80Gbit/s using a combination of nonlinear compression and pedestal suppression. Further, the same device was used to significantly enhance the performance of an OTDM demultiplexer. In both cases, the use of a simple and compact fiber circuit significantly relaxed the severe design constraints for components within practical OTDM systems.
