Effect of four-wave mixing on WDM optical systems: a statistical analysis

Investigation Of Fwm Effect On Ber In Wdm Optical Communication System With Binary And Duobinary Modulation Format

“…As shown in figure.2a The third simulation is conducted for both binary & duobinary modulation format to investigate the variation in BER with dispersion for constant core effective area =80µm & channel spacing =0.35nm.In figure.3a the variation in BER with dispersion for constant core effective area=8µm & channel spacing=0.35nm for duobinary & binary modulation format is shown. As we know that less dispersion means all signals are in phase [7] .when signals are in phase then there is interaction between signal & it produces FWM product. FWM product result in increase in BER which affect WDM optical communication system [7].…”

“…As we know that less dispersion means all signals are in phase [7] .when signals are in phase then there is interaction between signal & it produces FWM product. FWM product result in increase in BER which affect WDM optical communication system [7]. In figure.3a it is found that for binary modulation BER reduce with dispersion up to dispersion=6ps/nm/km.…”

Fat‐tree‐based optical networks‐on‐chip with WDM: crosstalk noise exploiting

“…The FWM [20,21] phenomenon commonly exists in optical WDM system and has a considerable impact [22,23] on it. The generation of the FWM is mainly due to the third-order non-linear effect [24], many information carrying signals with closely spaced wavelengths are put into a single waveguide where they can interact with each other, and will create third-order harmonics named FWM lights.…”

“…Yet for all that, crosstalk noise is still an essential research topic for ONoCs_W since ONoCs_W encounter inevitable crosstalk noise [10]. This crosstalk noise includes the traditional linear crosstalk noise and the non-linear crosstalk noise mainly created by the four-wave mixing (FWM) effect [11,12]. They are produced continually and accumulate in the process of signals transmission, result in information carrying signals failing to transmit without fault as well as optical signal-to-noise ratio (OSNR) diminution, and eventually attenuating the performance of the ONoCs_W such as scalability and stability.…”

Effect of Four Wave Mixing in WDM Systems for Higher number of Channels

“…However, there are exceptions arising from the interactions between light waves and the material transmitting them, which can affect optical signals. These processes generally are called nonlinear effects because their strength typically depends on the square (or some higher power) of intensity rather than simply on the amount of light present [4]. The nonlinear effects degrade the system performance.…”
