Abstract :
|
This paper introduces the nonlinear optical effect known as four wave mixing (FWM). In wavelength division multiplexing (WDM) systems four wave mixing can strongly affect the transmission performance on an optical link. In this paper, we investigate the effect of input signal power on the optical powers of the signals generated corresponding to signals for the four wave mixing effect. Here power signals P321 and P332 have been investigated and it has been found that P332 is almost proportional to the input power emphasizing that the power signals as small as 20pW could be observed for input signal powers at receiver unit.
