Phase-modulated photon antibunching in a two-level system coupled to two cavities

Phase-modulated photon antibunching in a two-level system coupled to two cavities Nonclassical light fields can be generated from two coupled cavities that are interacted with a two-level system. This scheme is drawing extensive attention because the mode coupling can reduce the requirement of coupling constants between the light fields and the two-level system. However, the effect of phase differences between different coupling constants on photon antibunching is always neglected. Considering a two-level system interacting with two coupled cavities, we analyze the statistical properties of the cavity field and show that the photon antibunching can be affected by the phase differences of coupling constants between the two-level system and the cavity modes, or between the cavity modes and the driving fields, and thus we can engineer the phases to optimally modulate single-photon sources or nonclassical light fields. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review A American Physical Society (APS)
