Impact of Optical modulation formats on SPM-induced limitation in dispersion-managed Optical systems - a simplified model
IEEE LEOS Workshop on Advanced Modulation Formats 2004, 1Co-Authors: S. Zhang, Rongqing HuiAbstract:This paper presents the numerical study that verified the simple relationship between launched Signal Optical Power and SPM-limited maximum transmission distance for various Optical modulation formats. It is also demonstrated that a proper selection of advanced Optical modulation format is critical to minimize the effect of SPM in high-speed dispersion managed Optical systems.

all Optical dpsk regenerative one to nine wavelength multicasting using dual pump degenerate phase sensitive amplifier
Journal of Lightwave Technology, 2014Co-Authors: Yan Meng, Junzi Lian, Ming Tang, P Shum, Deming LiuAbstract:We present theoretical investigation of all-Optical differential phase-shift keying (DPSK) regenerative wavelength multicasting using dual-pump degenerate phase sensitive amplifier (PSA), based on seven-wave model rather than traditional three-wave model. We first test the accuracy of the seven-wave model in the context of 40 Gb/s DPSK all-Optical regenerative multicasting. We find that the seven-wave model is more accurate than the three-wave model. Meanwhile, we successfully optimize Optical Signal Power, frequency spacing between two pumps, and regeneration capability of all multicasting channels. All-Optical DPSK regenerative one-to-nine wavelength multicasting can be successfully realized. Both eye diagrams and the calculated bit error rate curve demonstrate that the Optical Signal to noise ratio penalties of all multicasting channels are improved by around 3 dB. Finally, to the best of our knowledge, we investigate, for the first time, the effects of the high-order four-wave mixing (FWM) products on the evolution of pump-to-Signal intensity modulation transfer (IMT) and IMT from the pump to all wavelength-multicasting channels in a dual-pump degenerate PSA. We find that high-order FWM products contribute to the suppression of pump-to-Signal IMT after proper optimization of dual-pump's frequency spacing and Signal Optical Power. Both regenerative one-to-nine wavelength multicasting and pump-to-Signal IMT smaller than 1 can be simultaneously achieved under the gain saturation region.

100Gbit/s All-Optical Logic XOR Gate Based on CSRZ-DPSK Modulation Format
Journal of Hangzhou Dianzi University, 2012Co-Authors: Ma JunAbstract:Based on the non-degenerate four-wave mixing(FWM) effect in a highly nonlinear fiber(HNLF),high speed all-Optical logic XOR gate is realized.Because of the linear relationship of the complex amplitudes between output and input Signals in a non-degenerate FWM process,the generated idler Optical Signal carries the all-Optical logic XOR information of two input Optical Signals of carrier-suppressed return-to-zero differential phase-shift keying(CSRZ-DPSK) modulation format.We achieve all-Optical logic XOR gate at 100Gbit/s by numerical simulation and analyze the influences on the all-Optical logic XOR gate performance caused by the Signal Optical Power and probe wavelength.
