STUDY OF HIGH-ORDER ANTIBUNCHING OF TOTAL FREQUENCY PHOTONS IN A POLYATOMIC AND PHOTON INTERACTION SYSTEM

Abstract

This paper studies the antibunching properties of the total frequency photons generated by the atomic interaction system with N photons in the coherent state, the even-odd nonlinear coherent state and the squeezing state. On the basis of the criteria for the existence of high-order antibunching, we give an analytic expression for the general high-order antibunching of the system of N photons of total frequency at the input. The research results show that when the input modes are all in a coherent state, there is absolutely no antibunching property. In the case of input modes in the single-mode  coherent state, there will be no antibunching property, but as long as at least one photon in the additional nonclassical state is present, the antibunching property becomes evident when we choose value of amplitude, phase angle and suitable the degree of squeezing. Investigation of antibunching properties according the nonlinear even coherent state or the nonlinear odd coherent state has similar results.
