We experimentally investigate the transmission performance of a carrier-reuse WDM passive optical network, where downstream data is modulated on the optical subcarrier. Two different optical network unit (ONU) structures based on injection locked and directly modulated FP-LDs are studied. The results show that the effect of the residual data carried on the reused optical carrier can be suppressed...
This paper reviews and analyzes various light source schemes for high speed WDM passive optical networks in terms of configuration, performance and cost, including self- seeding of reflective semiconductor optical amplifiers (RSOAs), carrier distribution, remote external seeding of Fabry-Perot laser diodes (FPLDs) and downlink carrier remodulation.
We experimentally evaluate the performance of Fabry-Perot laser diodes (FPLDs) injection locked by spectrum sliced ASE noise for WDM-PON. Results show that the performance of the injection locked FPLDs is significantly improved by optimizing their front-facet reflectivity, operation temperature and bias current.
We demonstrate the use of an injection-locked Fabry-Peacuterot laser diode with electronic feedback for base-rate clock recovery in Ntimes10 Gb/s optical time-division-multiplexing (OTDM) systems. Injection-locking enhances the resonance frequency of the laser and the electrical feedback achieves strong resonance at the base-rate frequency of the injected data streams, enabling ultrastable electrical...
