We theoretically demonstrate that Kerr nonlinearity in optical circuits can lead to both resonant four-wave mixing and photon blockade, which can be used for high-yield generation of high-fidelity individual photon pairs with conjugated frequencies. We propose an optical circuit, which, in the optimal pulsed-drive regime, would produce photon pairs at the rate up to 5 × 10 s (0.5 pairs per pulse) with [Formula: see text] for one of the conjugated frequencies. We show that such a scheme can be utilised to generate colour-entangled photons.
我们从理论上证明，光学电路中的克尔非线性可导致共振四波混频和光子阻塞，这可用于高保真地高效产生具有共轭频率的单个光子对。我们提出了一种光学电路，在最佳脉冲驱动模式下，该电路将以高达5×10⁻¹⁰秒⁻¹（每个脉冲0.5对）的速率产生光子对，其中一个共轭频率的[公式：见原文]。我们表明，这样的方案可用于产生颜色纠缠光子。
