Degenerate Four Wave Mixing (DFWM) and Nearly Degenerate Four Wave Mixing (NDFWM) have attracted a considerable attention in non-linear optics. DFWM has found several applications in phase conjugation, used in real time holography and adaptive optics. To realize a higher amplification of the conjugate wave, semiconductor amplifiers have been used. A theoretical analysis of the NDFWM process has been presented by Agrawal [1]. Here, an experimental and theoretical analysis of NDFWM in Distributed Feedback (DFB) lasers is proposed, where the FWM efficiency is enhanced by the cavity feedback mechanism.
