论文摘要
我们研究了双腔光学系统中二阶相关函数的行为，并将退化的光学参数放大器（OPA）放置在每个腔中。第一个腔是由弱经典激光场驱动的。观察到这两个耦合腔中强光子抗挑战效应的发生。对于适当的光力耦合强度以及光子跳过程的值，该系统可以表现出非常强的光子抗启动效果。我们的研究还表明，与仅在强耦合方案中发生的常规光子阻滞相比，与常规的光子阻滞相比，非常规光子阻滞发生在两个耦合中，即弱耦合以及强耦合方案。在非常规的光子阻滞机理下，我们获得了非常强的光子抗挑战效应，而不是常规的光子阻滞机制。我们的研究还可以用于在耦合非线性光力系统中产生单光子。
We study the behaviour of the second-order correlation function in a double cavity optomechanical system and a degenerate optical parametric amplifier (OPA) is placed in each cavity. The first cavity is additionally driven by a weak classical laser field. The occurrence of strong photon antibunching effect in these two coupled cavities is observed. For suitable values of optomechanical coupling strength as well as photon hopping process, the system can exhibit a very strong photon antibunching effect. Our study also shows that the unconventional photon blockade occurs in both coupling, i.e. the weak coupling as well as in the strong coupling regimes as compared to the conventional photon blockade which occurs only in the strong coupling regime. We get a very strong photon antibunching effect under the unconventional photon blockade mechanism than the conventional photon blockade mechanism. Our study can be also used for the generation of single photon in coupled nonlinear optomechanical systems.
