Abstract
A new scheme of the entangled photon states re-generation the dynamic simulation of light traveling in nonlinear fiber optic ring resonator incorporating an erbium-doped fiber (EDF) has been investigated. We have shown that the weak entangled photon states can be recovered after circulating in the amplified fiber optic medium. The output entangled photon states can be re-generated by adjusting the polarization controller of the amplified photons, where the re-generated entangled states can be controlled and performed. The ring-cavity lifetime is much longer than the Kerr-effect response time of the fiber ring. The results obtained have shown that this system can be used to achieve the recovered polarization entangled states with the obtained high gain. The amplifying noise has also been detected and seen on the spectrum output. This is affected to the entangled photon visibility, which is discussed.
