Different optical fiber nonlinear coefficient experimental measurements

In this paper, nonlinear nature of three different optical fibers: Corning SMF-28 ultra optical fiber, Draka enhanced single-mode optical fiber and highly nonlinear fiber has been studied experimentally by the measurement of nonlinear coefficient using four wave mixing process. Obtained results have shown that measured values of the nonlinear coefficient are 0.78 W

for SMF-28 fibers, 1.45 W

for enhanced singlemode fiber and 10.68 W

for highly nonlinear fiber, that conforms to typical values.
