  4. Abstract:
  5. In the present study, the antibunching effect is considered in a parity time (PT)-symmetric system, using the recently proposed non-Hermitian model for resonant cavities. The model consists of a cavity coupled to an optomechanical system by a chiral mirror, with both cavities being driven coherently. The nonreciprocal coupling strength between the two cavities leads to the generation of the non-Hermitian but PT-symmetric model. The optimal conditions of strong antibunching are calculated in this system, and then the antibunching effect is considered using the two-photon correlation function and the Wigner function. The results showed that this model presented the best control over the strong antibunching effect by tuning the nonreciprocal coupling strength between the cavities, the strength ratio between the two fields, and nonlinearity strength-an outcome inaccessible by the Hermitian system. © 2017 Optical Society of America
