Four-wave mixing in wavelength–division- multiplexed soliton systems: ideal fibers
نویسندگان
چکیده
Analytic expressions for four-wave-mixing terms in an ideal, lossless wavelength–division-multiplexed soliton system are derived with an asymptotic expansion of the N-soliton solution of the nonlinear Schrödinger equation. The four-wave contributions are shown to grow from a vanishing background and then to decay. Their importance becomes evident in real, nonideal fibers, where they grow by an order of magnitude and equilibrate to a stable value as an effect of periodic amplification. © 1997 Optical Society of America [S0740-3224(97)02007-9]

متن کاملSuppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System
Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...

The performance of an optical wavelength division multiplexed communication system is analyzed taking the four wave mixing (FWM) effect into account. Also it is found that the efficiency of FWM generation can be greatly reduced by making the spacing between channels unequal. Taking into account the various channel spacing schemes and various distribution of different dispersion type optical fib...
متن کاملFour-Wave Mixing in Optical Fibers and Its Applications
When a high-power optical signal is launched into a fiber, the linearity of the optical response is lost. One such nonlinear effect, which is due to the third-order electric susceptibility is called the optical Kerr effect. 1), 2) Four-wave mixing (FWM) is a type of optical Kerr effect, and occurs when light of two or more different wavelengths is launched into a fiber. Generally speaking FWM o...
