Abstract

The preparation of correlated multiphoton sources is an important research topic in quantum optics and quantum information science. Here, two-mode correlated multiphoton bundle emission in a nondegenerate multiphoton Jaynes-Cummings model, which is comprised of a two-level system coupled with two cavity modes is studied. The two-level system is driven by a near-resonant strong laser such that the Mollow regime dominates the physical processes in this system. Under certain resonance conditions, a perfect super-Rabi oscillation between the zero-photon state $|0\rangle_{a}|0\rangle_{b}$ and the ($n+m$)-photon state $|n\rangle_{a}|m\rangle_{b}$ of the two cavity modes can take place. Induced by the photon decay, the two-mode correlated multiphoton bundle emission occurs in this system. More importantly, the results show that there is an antibunching effect between the strongly-correlated photon bundles, so that the system behaves as an antibunched ($n+m$)-photon source. The work opens up a route towards achieving two-mode correlated multiphoton source device, which has potential applications in modern quantum technology.
