Enhancement of four wave mixing characteristic in Semiconductor Optical Amplifier using Fiber loop mirror

We investigate the effect of the input wave power, wavelength detunes between the two source waves and the conjugate wave power to conversion efficiency. The essential part of the investigation is about suppression ratio of pump power and conjugated wave power. The proposed setup success for suppress the pump power and increase the conjugate signal in wavelength detuning of 1.4 nm. It is due to loop mirror that act as a reflector where depend to the high birefringence of the Polarization Maintaining Fiber (PMF) and the polarization controller.
