Abstract

In this article, suppression of FWM been proposed with cost effective technique of DCF and FBG.At high powers,\nmaximum FWM power and at low powers very less nonlinearity is observed. Comparison of single tanh apodized FBG,\nconventional FBG and FBG+DCF module is carried out. It is concluded that DCF+FBG module is best to suppress FWM.
