ABSTRACT⎯We improved the performance of the spectrum-sliced light source for wavelength-divisionmultiplexed passive optical networks by employing a FabryPerot laser diode (FP-LD). We found that FP-LDs can suppress the intensity noise as significantly as using a gainsaturated semiconductor optical amplifier. The transmission characteristics were measured and analyzed both with and without employing an FP-LD.Keywords⎯Wavelength division multiplexed-passive optical network (WDM-PON), spectrum-slicing, amplitude squeezing, semiconductor optical amplifier (SOA).
Seung-Hyun Cho et al.371ABSTRACTWe propose and demonstrate a fabrication method of chirped fiber gratings by a thermal diffusion process. The method could suggest a direction for a simple and costeffective implementation of chirped fiber grating-based devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
