Abstract

An efficient system for characterization of nonlinear coefficient parameter in a highly nonlinear fiber (HNLF) and Zirconia-Erbium co-doped Fiber (ZrEDF) are demonstrated by using four wave mixing (FWM) technique. Interlaboratory comparison show that the values found with our method are in good agreement with the manufacture. Based on the FWM techniques, the nonlinear coefficient of HNLF is 10.7 W-1km-1 with the dispersion slope @ 1550 nm of 0.007 ps.nm-2km-1, zero dispersion wavelength (ZDW) of 1531 nm are obtained which is 0.93% error compared to the manufacturer’s datasheet values. For a 4 m long ZrEDF, a non-linear coefficient of 7.164 W-1km-1 @1565 nm is measured, along with chromatic and slope dispersion values of 1.03 ps/nm.km and 9.34 x 10-3 ps/nm2.km, which agree with the theoretical predicted values.
