Abstract
A new technique of an entangled photon pair generation using an all fiber optic scheme is presented. The proposed system is consisted of a fiber optic Mach-Zehnder Interferometer (MZI) incorporating with a fiber optic ring resonator. The Kerr nonlinearity effect in the fiber ring resonator is exploited for the generation of two independent squeezed beams. The advantage of such a system is that it requires a simple arrangement without any optical pumping part and bulky optical components. Polarized light pulse trains are launched randomly into a MZI which one part of them is delayed in the longer path. The output pulses from both arms of the MZI are entered into a nonlinear fiber optic ring resonator. Where the superpositions of light pulses in a nonlinear fiber optics ring resonator are randomly occurred which is formed the entangled photon pairs. A polarization controller controls polarization states of light pulses while circulating in the ring resonator. The entangled photons are seen on the avalanche photo-detector, which is shown in good agreement with the previous works. © 2007 IEEE.
