The general form of U-CPE is presented and the optimal algorithm with better performance and lower complexity is proposed and analyzed. Simulation results show low OSNR penalty can be obtained for various modulation formats.
We propose a novel DWDM over OCDMA scheme with parallelly combined Super-Structured Fiber Bragg Grating (SSFBG) based encoder/decoders. In our scheme, a group of SSFBGs with the same code but different central reflection frequencies are parallelly combined together to support larger number of DWDM channels. The number of DWDM channels per code can be increased without increasing the chip-rate of SSFBG...
In this paper, we propose and demonstrate the practical all-optical wavelength multicasting scheme based on the four-wave mixing (FWM) effect in both a highly nonlinear fiber (HNLF) and a semiconductor optical amplifier (SOA). Then we carry out comprehensive comparisons of the performance differences between using the HNLF and SOA for this proposed multicasting scheme. Seven multicast channels are...
We present a novel scheme to construct non-wavelength-selective optical network unit (ONU) in hybrid wavelength division multiplexing and optical code division multiple access based passive optical networks (WDM/OCDMA-PON) by making use of the broad spetrum band of superstructure fiber Bragg gratings (SSFBGs). The experiment results reveal that the spectrum-sliced encoded signals from different wavelength...
