Optical fiber nonlinearity estimation through four-wave mixing

Abstract EN

-Optical wavelength converters are very important devices in optical Dense Wavelength Division Multiplexing (DWDM) Systems.

Among numerous wavelength technologies Four-Wave Mixing (FWM) in optical fibers is attractive because it offers strict transparency to amplitude, frequency and phase.

They also have the ability to convert multiple wavelengths simultaneously and to invert optical spectra.

Four-wave mixing conversion efficiency depends upon fiber nonlinearity.

The effects of fiber nonlinearity play a decisive role in the design and performance of modem optical communication links.

So it is important to measure the nonlinear promising technique for determining fiber nonlinearity (γ).

This paper investigates a way of estimating fiber nonlinearity through four-wave mixing process.
