Abstract
We have analyzed the dissipative effect of the entangled photons generated by a nonlineaoptical ring resonat ofrom a non-degenerate four-wave mixing (FWM) process. The system and reservoi Hamiltonian are established in the interaction picture. To eliminate the reservoi operators, the Markov approximation is used and result them in a Linblad form in the maste equation. Consequently, the positive P representation can recast this equation to the Fokker-Planck equation, and then the stochastic differential equations i.e., the entangled photon state equation of motion for photons propagating in the fiber, are obtained and easy to analyze numerically. Results obtained have shown that the entangled strength measurement depends on three main factors; first the nonlinear susceptibility of the third harmonic generation, second the damping rate that represents loss of energy from the system to the reservoir, and final the diffusion of fluctuations in the reservor into the entangled photon modes. © 2009 Elsevier GmbH.
